How To Replace Tapered Auger Bit Teeth

Our Digga tapered auger bit teeth are defined by their tapered shape and are used on our earth/rock combo range of auger bits (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 Bit Teeth

Tapered auger bit teeth are found on our earth/rock combo auger bits. 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 Bit Teeth

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

1. Position the auger bitso 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 bit 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.

CORRECT WAY OF INSTALLING TAPERED AUGER BIT TEETH

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 Bit Pilot

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

1. Move the auger bit 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.
