How to Replace DR Auger Rock Picks (Dedicated Rock Augers)

Rotating rock picks, are the auger teeth used on our Digga dedicated rock augers (DR) for drilling from soft rock to hard fracturable rock.

Here are some things you can observe to determine whether the rock picks are worn: The teeth need to rotate while drilling to maintain an efficient cutting tip. The tungsten tip and tooth should be evenly pointed. Poorly maintained teeth reduce cutting efficiency and wear out faster costing time and money. We recommend you replace worn teeth immediately!

Tip: the outside teeth (C) will wear the fastest as they are travelling the greatest distance so will need replacing more often. Try swapping the outer tooth for an inner tooth to keep the wear even. Always use your best teeth on the outside pockets.

Here are some examples or rotating rock picks in various states of wear.

Tooth A has not been rotating in the pocket and as a result the tooth is uneven and will cut poorly. We recommend changing this tooth. You may also notice if the tungsten tip has been worn down and flattened, we recommend replacing the tooth.

Tooth B indicates that they have been rotating in the pocket and “self-sharpening”. Tooth is good.

Tooth C has been rotating in the pocket and wearing evenly. This tooth is still good but must be inspected regularly as it is nearing its wear life.

In summary, the best course of action would be to remove teeth A and C. Discard A and place C in the pocket vacated by A. Place a new tooth where C used to be.  

Tip: Each time the auger is brought out of the hole to remove spoil, use a soft copper or dead blow hammer to tap all teeth ensuring they are rotating freely in their pockets. This will encourage even wearing around the tooth.

Removing Rock Pick Auger Teeth

Rock picks are found on our dedicated rock augers. Follow either of the below steps to remove them.

Option 1: Place a rotating pick removal tool in the groove of the rock pick. Use a hammer to strike the tool’s strike point (fig.1) to tap it out. 

Option 2: Alternatively, use a pin punch & soft head mallet on the back of the rock pick to knock it out. (Fig.2)

Installing Rock Pick Auger Teeth

Once removed, clean the pocket and follow the below to replace the tooth.

1. Replace the rock pick and knock it in all the way with a soft head mallet.

Note: Rotating picks must rotate freely. Never use grease or lubricants, as this will cause dirt to bind the rock pick and prevent it from rotating.

Replacing the Auger Pilot

Replacing the pilot is similar on all augers and a pretty much foolproof.

1. Move the auger into position so the cutting head is easily accessible ensuring it is stable and secure. Remove the pilot by removing the bolts holding it in place and lift it out of place. Once removed, replace it with a new one and secure it with the provided nut and bolt.

Before starting to drill, please ALWAYS ensure that all rock picks and pilot are locked in tight.

Tip: After each day, hose down your auger head to remove dirt / dust from around the teeth. Left alone this dirt can become as hard as concrete locking the teeth in place. Next time you’re driiling your teeth won’t rotate and you may be up for new teeth or an expensive repair.

Why buy Australian-Made Machinery Attachments?

Let’s face it, we’ve all been there: weighing up buying a cheaper imported product rather than purchasing from an Australian-owned brand. But is it worth the risk?

There are some great reasons why you should be buying Australian made products where you can. Especially, when it comes to larger investments like machinery and construction equipment that is utilised on a daily basis. 

Your choice to purchase Australian made has a far-reaching affect which goes beyond simply keeping a company like Digga in business. 

While buying local means you are getting a quality product which has been built for our conditions and support is close by should you need it - it is the knock-on effect on our economy which isn’t so apparent at first sight.

Supporting Local Manufacturing, the Economy and Jobs in Australia 

Take Digga as an example, employing over 200 people in our Queensland manufacturing facility is just the start of your contribution when you purchase Digga. With branches also in NSW, VIC and a distributor in WA who employ local Australian staff. Now consider all the money these people put back in the local economy every day. From doing the shopping, to having a cold one at the pub, to taking the family camping or getting their car serviced at a mechanic. We’re talking about 10’s of millions of dollars every year being spent by our staff back in the local economy. Now imagine if Digga was based overseas, all this money would be spent in that country. Now multiply this by the 40 years that Digga have been manufacturing in Australia and you get 100’s of millions of dollars which has gone back into the economy. 

Furthermore, as an Australian owned company any profit made by Digga stay in Australia and is re-invested in the community. 

Considering the effects of the pandemic on our economy, there has never been a better time to ensure that your money stays in Australia and helps support local businesses and the people who own them. It will help our country recover faster. Yes, you may pay a few extra dollars for a quality Australian made product, but at what cost to our economy?

Remember that it is our friends, our loved ones, and our kids who work at these small businesses. By buying an imported product are you putting the people you care about out of a job? Think that buying an imported attachment for your excavator won’t affect your local pub? Think again! Our economy is one big circle. Taking money out of the circle affects every Australian.

Supporting Manufacturing, Also Means Supporting its Suppliers.

But wait, that’s only the start. With Digga manufacturing around 80% of all components in-house comes a massive supply chain to keep the “beast fed”. Over 300 tonnes of steel makes its way into our facility each month via local suppliers. These suppliers employ delivery drivers, warehouse staff, admin, finance and salespeople to service our account. And that’s just one of 100’s of local suppliers which Digga utilises to produce over 41,000 different components. Then there are the numerous food trucks which come in each day to keep our troops fed, there are cleaners, IT services, office suppliers, gardeners just to name a few. Each and everyone of their employees spends money in their local economy helping small and large Australian businesses.

When we read or hear of yet another Australian manufacturer moving their production overseas the media only ever mention the direct job losses. The fact is, that the in-direct jobs loses and effect on local economies is far greater than most of us realise. A company with 200 workers lost to another country could see 1000’s more Australians lose their jobs as result of the knock-on effect. That’s 1000’s of jobs now created in another country.

We all know someone who has been made redundant from their job, is it possible that our decision to purchase an overseas product regardless of what it is, could have played a small part in it?

It makes you wonder whether saving a few dollars on a cheaper imported product is really worth considering all the other advantages which come with buying Australian made

After Sales Service

With local manufacturers, parts supply, service, and warranty are guaranteed by the company. There is nothing worse than being stuck waiting for parts to come in from overseas when you are trying to avoid costly downtime. 

When you invest in equipment, you would also want to maintain it to keep it functioning at its best to ensure maximum returns – which is why the option for a local service is crucial. At Digga, a service division MASR with in-house and onsite service vans and trucks is fully operational in metro QLD, NSW, and VIC. We’re here for any spare parts or repair enquiries you may need. With over 1.4 million individual items in stock, your equipment would be back working in no time. 

Quality, Safety & the Environment

When you are running a business, quality is priceless and if your equipment is not working, neither are you.

When it comes to the quality of products manufactured in Australia, the Australian Law provides stringent quality, safety and environmental guidelines and policies that local manufacturers like us need to adhere by. 

Besides that, Digga with its ability to manufacture over 80% of components from raw material to finished goods in-house, is able manage quality-control with precision across our range of products.

Also, being part of the ISO 9001 quality management standards, Digga is committed to maintaining excellence and we are uncompromising in our dedication to provide high quality competitively priced attachments to the Australian market.

Customisation and Adaptability to the Australian Conditions

Having a locally-based R&D Department always looking to make improvements and stay ahead of the game, means being able to supply products, which suit the customers individual needs as well as the products being ideally suited for Australian conditions. When it comes to earthmoving, farming and construction the Australian environment is considered to be one of the harshest in the world. Imported products may not withstand those conditions.

With a dedicated team of engineers and technical staff, at Digga we are able to come up with  original, cutting-edge designs and functionality improvements, and fully test performance optimisation. Using leading software, finite analysis and 3D modelling technology we are able to maintain a competitive edge by greatly reducing the cost and time of developing new parts and products.

By having this flexibility at hand, we are also able to offer custom solutions for products like augers, which can vary in their widths, lengths and cutting heads depending on the customer’s wishes.

So let’s sum it up, why opt for Australian Made machinery attachments?

√ Get quality equipment, which is safe and manufactured under good conditions

√ Support local manufacturing and the Australian economy, helping to create jobs in Australia

√ You can count on reliability as well as warranty on your investment

√ Local service & support means fast repairs and less downtime

√ Get customised attachments that are ideal for the Australian environment

How To Replace Tapered Auger Teeth (Earth/Rock Combo Augers)

Our Digga tapered auger teeth are defined by their tapered shape and are used on our earth/rock combo range of augers (RC).

Tapered teeth will wear most on the edges above the carbide tip. You may notice the teeth scalloping out around the edges and forming a crease around the tooth.  Please remember that it becomes essential to change the tooth as soon as you notice the carbide tip is either gone, chipped, damaged or cracked.

If you notice excessive wear on a single tip carbide tooth and its pocket – we recommend replacing it with a double tip carbide tooth.

Removing Tapered Auger Teeth

Tapered auger teeth are found on our earth/rock combo augers. Follow these first steps to remove them.

1. Place a pin punch or centre punch in the hole at the base of the tooth holder.

2. Ensure the rounded side of the punch is facing the bottom of the pocket and the flat side against the base of the tooth.

3. Use a hammer to tap the punch into the hole to dislodge the tooth.

4. Remove the tooth.

Installing Tapered Auger Teeth

Once removed, clean the pocket and follow the steps below to change the teeth.

1. Position the auger so the cutting head  is easily accessible. Secure it in place, to ensure it cannot fall.
2. Place the teeth in the pockets ensuring the ridge of the tooth aligns with the ridge of the pocket.

3. With the auger tooth placed in the pocket, knock the tooth in with a soft head mallet until the ridge of the tooth is past the top of the pocket’s ridge. Using a standard hammer will shatter the tungsten tips.
4. Ensure all teeth are secured tightly before starting to drill.


Note, that the following configuration of double and single tip teeth, as well as the depth and direction need to be considered too.

Replacing the Auger Pilot

Replacing the pilot is similar on all augers and a pretty much foolproof.
1. Move the auger into position so the cutting head is easily accessible. Remove the pilot by unbolting it. Once removed, replace it with a new one and secure it with the provided nut and bolt.

Before starting to drill, please ALWAYS ensure that all teeth and pilot are locked in tight.

There you have it. Make sure to always look after your equipment so it keeps running at its best performance. Got questions? Reach out to us should you have any trouble removing or installing your auger teeth. For spare parts or service enquiries, head to our website or give us a call at 1300 2 DIGGA.

How to Replace Bladed Auger Teeth (A-series Augers)

If your A-series auger teeth look anything like the below you should replace them rather sooner than later.

The tungsten tip A-Series Auger tooth will wear most on the leading edge of the tungsten. You should see a valley type pattern on the underside of the teeth.

In the following, you will find a guide on how remove and install worn auger teeth for A-series augers. If you need to install tapered teeth or rotating rock picks check out our blog. In the meantime, you can also watch our video

Removing Bladed Auger Teeth

Bladed teeth are found on all A series earth augers. Follow these first steps to remove them.

1. If a nylon pin (Pinloc) is in place, remove it using a hole puncher or by breaking the pin. Pinloc is available on A4 augers only.

2. Place a punch in the groove on the back of the tooth, Tap on the back of the punch with a hammer to dislodge the tooth. This should also release the Rubberloc, if used.

3. If the tooth is jammed or difficult to remove, a pin punch or centre punch can be placed at the base of a tooth (to dislodge it), and tapped out with a hammer.

Installing Bladed Auger Teeth

Once removed we move onto replacing the teeth. Are you adding rubber or pin loc for additional hold? Then make sure to check out the rubberloc & pinloc steps below as well.

1. Place the auger so the head is easily accessible. Secure it in place, to ensure it cannot fall.

2. With the auger hub on the ground and the auger head facing up, turn the tooth so that the punch groove is facing up. For a more in-depth illustration, move to the bottom of the page.

3. Place the tooth in the pocket, and knock it in with a soft head mallet. A standard hammer will shatter the tungsten tips.

4. Ensure all teeth and pilot are locked in tight before starting to drill.

While the vulcanised rubber pads will hold the tooth firmly in place for most applications, we recommended that you use an additional method to secure the tooth. The following steps show you how to install the rubberloc and pinloc options.

Adding Rubberloc 

Follow these steps to add Rubberloc for additional hold.

1. Cut the rubber approximately 3mm shorter than the tooth width. Moisten the rubber in water to assist in tooth insertion. Do not use oil. 

2. Insert the cut piece of rubber through the horizontal hole inside the tooth holder. Place the teeth in the pockets.

3. With the auger tooth placed in the pocket, knock the tooth in with a soft head mallet.

4. The rubber folds back and compresses between holder and tooth locking the tooth firmly in position.

Adding Pinloc (A3 & A4 series auger only)

Follow these steps to add the Pinloc. Pinloc is used for drilling in hard to very hard soils and rock, or for tree roots where reversing the auger is necessary.

1. Once the teeth have been replaced according to previous steps, insert the Nylon Pin through the top of the pocket. 

2. Knock the pin in with a soft head mallet, to lock the tooth into place.

Ensure your teeth are installed correctly!

Correct way of installing bladed teeth.

When it comes to installing auger teeth, the right direction is crucial. Here’s how to correctly install A-series auger teeth.When the auger is in its drilling position, the cutting edge of each tooth should be pointing to the ground.

Incorrect way of installing the teeth.

The above tooth has been inserted incorrectly. Flip the tooth so that the cutting edge points towards the ground.

Note, that the following configuration of flat and chisel teeth, as well as the depth need to be considered too.

Installing the Auger Pilot

Finally, removing and installing the pilot is a very simple process as follows.

1. Place the pilot on the bottom of the auger (in the centre) and secure it with the nut and bolt.

Be a good mate and ask R U OK

Did you know that tradies are twice as likely to commit suicide than other people in Australia? Statistic surrounding suicide and mental health within the construction industry are quite confronting.

In this male dominated industry people are often asked to ‘toughen up’ with negligence of possible consequences and people’s feelings, what is happening in their lives and why they might be feeling depressed or not themselves.  

And let’s face it. It’s been a rough couple of months for everyone during this pandemic with impacting changes in both our work and personal environment. Which is why we should all be looking out for each other and let our mates know that it’s okay not to be okay.  

At Digga we want to encourage you to be a good mate and ask ‘R U OK’. As part of R U OK day we want to promote awareness for people that may be at risk of mental health issues or potentially suicide in our community. 

Here are some useful tips on how to ask R U OK, as well as how to act when we’ve been told “No, I am not ok.” Follow theses 4 Steps (Source:

1. ASK R U OK?

  • Be relaxed, friendly and concerned in your approach. 
  • Help them open up by asking questions like "How are you going?" or "What’s been happening?"  
  • Mention specific things that have made you concerned for them, like "You seem less chatty than usual. How are you going?" 


  • If they don’t want to talk, don’t criticise them. 
  • Tell them you’re still concerned about changes in their behaviour and you care about them. 
  • Avoid a confrontation. 
  • You could say: “Please call me if you ever want to chat” or “Is there someone else you’d rather talk to?” So, make sure to look after your employees, your workmates as well as your boss. If you notice something’s not right, don’t be afraid to approach them and ask whether they are doing ok. 


  • Take what they say seriously and don't interrupt or rush the conversation.
  • Don’t judge their experiences or reactions but acknowledge that things seem tough for them.
  • If they need time to think, sit patiently with the silence.
  • Encourage them to explain: "How are you feeling about that?" or "How long have you felt that way?"
  • Show that you've listened by repeating back what you’ve heard (in your own words) and ask if you have understood them properly.


  • Ask: “What have you done in the past to manage similar situations?”
  • Ask: “How would you like me to support you?"
  • Ask: “What’s something you can do for yourself right now? Something that’s enjoyable or relaxing?”
  • You could say: "When I was going through a difficult time, I tried this... You might find it useful too."
  • If they've been feeling really down for more than 2 weeks, encourage them to see a health professional. You could say, "It might be useful to link in with someone who can support you. I'm happy to assist you to find the right person to talk to.”
  • Be positive about the role of professionals in getting through tough times.


  • Pop a reminder in your diary to call them in a couple of weeks. If they're really struggling, follow up with them sooner.
  • You could say: "I've been thinking of you and wanted to know how you've been going since we last chatted."
  • Ask if they've found a better way to manage the situation. If they haven't done anything, don't judge them. They might just need someone to listen to them for the moment.
  • Stay in touch and be there for them. Genuine care and concern can make a real difference.

If you’re worried about your mate and have a feeling they need professional support, encourage them to connect with a trusted health professional like their doctor or other support like Lifeline at 13 11 14. Further support tools can be found here:

The Latest Auger Alignment System on the Market - HALO

Now available Digga Halo Auger Alignment System

Have you heard of HALO, the biggest innovation in pendulum drilling in the past two decades? HALO is Digga’s brand new Auger Alignment System. 

HALO has been designed to save operators time and money. It helps you drill straight holes and therefore provides a number of advantages to the earth drilling industry.

Its benefits include, amongst others, reducing the number of in-hole angle adjustments which can create an oversized hole, also reducing the amount of concrete required to fill the hole. Not drilling straight can additionally cause sideload on the auger bit and drive, potentially causing damage and expensive repairs. With HALO operators drill more efficiently, as you can return to drilling faster after returning the auger into the hole.

Another great advantage is you won’t need a spotter with a spirit level guiding you through the hole. So, if you’re trying to save on labour costs, HALO is the way to go - remember HALO does not take holidays or sick leave!

Digga Halo Auger Alignment System

So, how does it work?

It’s simple: Chase the Green, Live the Dream!

A band of green LED lights indicate when the unit is in a plumb position, while a sequence of red and green lights guide you back to plumb when the unit goes out of alignment.

HALO has been programmed to show all green LED from 0°to 1.5°of incline. After 1.5°the LEDs will show a sequence of red and green lights.

These lights move around the hood to indicate which way to move the drive to return to plumb. The red and green lights are always opposite each other, thus if the operator can only see the red light, he or she will surmise the location of the green and be able to “chase” it.

Digga Halo Alignment System- chase green LED lightsWhat components is HALO made up of?

The brains behind HALO lie in the hood box, which is situated inside the hood. It includes 6 sensors to accurately measure inclination to +/-.25°. HALO utilizes a microprocessor and “Sensor Fusion” to bring together inputs from multiple sensors to form a single output which is more accurate and less prone to false readings than single sensor models.

A one-piece LED ring made from polycarbonate will allow you to see the HALO from a distance and also in bright daylight. The LED lights are a high-resolution single die LED strip featuring 3 LEDs per pixel. The LED strip is then covered by a polyurethane compound making the whole unit dust and waterproof. It’s then recessed into the hood ring to protect it from damage and the bottom ring is bevelled to allow better visibility of the lights when the drive is being used with long extensions.

A lead-in power cable, which extends around 200mm from the hood, allows you to power the HALO. This then gets connects to either a power cable & extension back to your cab’s cigarette lighter or to a HALO battery, which lasts up to 8 hours. The lead-in cable has a yellow sheath to make it more visible to the operator and can easily be tucked into the hood when transported or stored.

How does HALO compare to other alignment systems on the market?

There are several advantages of incorporating an alignment system into the hood. It costs significantly less than traditional systems by eliminating the need for a costly in-cab display screen. 

In-cab display screens also require you to constantly take the eyes of the job, which is unsafe and tiring over time. HALO sits right in the hood of your drive (above the auger and drilling hole), so it is highly visible while drilling. We consider HALO to be an upgrade from existing technology on the market. Why use outdated technology when there’s more affordable and effective options, right?

Research, Development & Testing

Since its inception in 2016, HALO has gone through a wide range of testing and design upgrades to ensure the product taken to market works as intended, is free from defects and is durable. Some of the tests have included, water, vibration, and heat testing as well as longevity testing.

Over 50 units have been out in the field with customers since November 2019. Very few issues were reported with all concerns rectified with our latest version HALO.

Digga Halo Testing

These are some comments we have received from our Testers in the last couple of weeks: “Would be lost without the HALO, I would dig over a couple of thousand holes a year and this has sped up time and production.” – Ritchey Fencing.

“The main benefit I get out of it, is that it takes away the need to use another operator guiding me through the holes. This really saves me a lot of labour costs.” – Bobs n 2 Sons Excavations.

Why is it important to drill straight? And what happens if you don’t?

Auger drives are pendulum drills designed to hang freely from the machine mount. You need to consider, that excessive side load may result in bent auger flights, pipe and hubs as well as potential damage to the auger drive shaft, seals and gearbox. When you are drilling especially into hard ground this may also cause socket and pilot breakage. HALO makes sure you are aligning your auger and drive correctly, to avoid damages and drill which much better performance.

BONUS WITH BATTERY: Zero-ing Function lets you drill at an angle!

For those of you, who are often required to drill on an angle for e.g. installing retaining walls or shade sails there is another bonus the HALO brings. With the purchase of a battery pack, the HALO can be set to a desired angle in inclination just by the click of a button.
So, let’s sum it all up. 

Why do YOU need HALO?

  • Drill straight and avoid side loading your auger, causing damage 
  • Never take your eyes off the job
  • No more in-hole angle corrections - use less concrete
  • Reduce costs & increase efficiency - no need for a spotter
  • Realign the auger faster when re-entering the hole - save time
  • Easy and no-fuss setup 
  • Drill at an angle with the battery option

The HALO system is out now for new Digga Drives PD3 to PD7, which suit most machines like skid steer loaders, mini loaders, tractors, and excavators around the 3 to 8 tonne range. We are looking at releasing HALO to their entire range of drilling drives in late 2020 and will be re-assessing retrofit options in the future.

Digga Tips - Servicing and Oil Change of your Digga Drive Unit

To ensure longevity and performance, it is crucial to service your Digga drive unit and change the oil in regular intervals as advised in the operator’s manual. While you might be wondering why, we have got all the answers for you.

When do I need to service my auger drive?

As advised in the operator’s manual, here is an overview of when to service your drive depending on your operating conditions.
When to Service Your Auger Drive Intervals

Why is gear oil important to ensure the longevity of my drive?

Essentially, the oil in your drive unit is independent to your hydraulic system. Meaning that the oil from your machine does not lubricate your drive unit.

As a result, your auger drive requires regular oil changes to remain in perfect working condition and to avoid damage to the gears.

What happens if my auger drive is not serviced regularly?

We have tested 3 drive units in our Hydraulic Cyclic Testing Unit where 10 years of wear and tear was simulated. Oil was changed in the drives at different intervals illustrating the wear caused by neglect. 
The images below illustrate the importance of regular servicing of your auger drive and what happens if failed to do so.


This is a gear from a drive which has been serviced as per the operators manual and shows very little wear with no more than bedin wear after 10 years of simulated augering. The oil was changed after 12 months and then every 2 years thereafter as per the operators manual.


The same drive submitted to the same workload as above over 10 years, with the oil changed only once - at 5 years. While the drive unit shows no decrease in performance, the gear shows visible wear which will deteriorate quickly, leading to total failure.


This drive has never been serviced. The image shows the damage to the gear, which causes total failure of the gearbox.

At Digga we offer ISO 320 Grade Mineral Oil in 1 litre, 2.5 litre and 5 litre containers.

Now also available: DIY Service Kits for Auger Drives from PDD to PD50!

How to Operate A Digga Bucket Broom

Having trouble operating your Digga bucket broom?

There are a few tips and tricks when it comes to brush adjustment & height, rotation direction and the broom emptying procedure. We've summarised them for you below.

Direction of travel and brush rotation

Always sweep at a high enough brush speed and low ground speed to effectively discharge the material being swept.

Brush height adjustment

Remove the handle pin, twist the handle, and replace the pin. Re-adjust the axle to the correct height using both handle adjusters. Return handles to their original position.

Correct Brush Height

Set the height of the brush so the bottom of the brush is approximately 30mm lower than the bucket cutting edge. The brush must be level.

Emptying Procedure

When the bucket requires emptying, stop the rotation of the brush, lift your loader arms and crowd the bucket forward so the Bucket Broom hood swings away from the bucket.

Examples of Damaged Bucket Brooms due to Incorrect Operation

If not used correctly, damage and expensive repairs can occur to the Digga bucket broom attachment. Below are some examples.

Broom 1 – Worn side rubber and side panel due to too much downward pressure and incorrect placement of the broom to the ground during operation.

Broom 2 – Worn Brush, starting to wear side panel.

Broom 3 – Worn the cutting edge (wear strip) to the point that the floor has started to wear away and edge is now non-existent. New bucket floor is required.

Broom 4 – Brush has been lowered to its maximum wear point and is now out of thread, a new brush is required.

Broom 5/6 – Strong wear to the rubber and side panel due to too much downward pressure and incorrect placement of the broom to the ground during operation.

Please always make sure to read the operators manual before operating your attachments! Should you have any questions, please don't hesitate to contact us anytime at 1300 2 DIGGA.
