An auger drill bit is used to bore holes in timber. It is great for drilling
holes in thatch poles to insert threaded rods.
The design is very similar to a forstner drill bit, as it ‘shaves’ itself
through the wood. A low rpm rotary drill with a planetary gearbox is required to
be used with auger drill bits.
What is an auger drill bit?
An auger drill bit is one of the very first types of drill bits used in the
carpenter industry to bore holes in timber.
A very early example of the auger drill
bit is the scotch eyed auger. The pilot guide is threaded to ‘pull’ the drill
bit into the wood. The cutting edge forms part of the auger helix to assist the
drill bit with the removal of shavings. Nowadays, auger drill bits
are used with powerful electric rotary drills to speed up the process of boring
Take care when drilling with auger drill bits. The auger drill bit tends to jerk
the rotary drill when drilling. Keep the rotary drill steady with both hands to
prevent wrist injury.
