Description
This is a description of an auger bit, which is a type of drill bit. The bit is 20mm in diameter and 460mm long. The bit has a hex shank, which is good for use in drilling holes in timber. The bit is designed to shave itself through the wood, and is best used with a low rpm rotary drill with a planetary gearbox.
Auger drill bit
Daimeter: Ø20.0mm
Working length: 460mm
Shank: Hex
Application:
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 holes.
CAUTION! 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.
