Extra Long Auger Bits - Set of 4

This set of 4 auger bits are the best that we have ever offered or tested and are perfect for quickly and accurately drilling deep holes through thicker stock. They can be used in a drill press or electric hand drill and are designed to be used on softwoods and hardwoods. The precise cutting geometry, a single cutting spur on the perimeter and a chisel like main cutter ensures accurate, clean holes while minimizing tearout on entry and exit of the hole. The cutting spur sits fractionally above the main cutter to ensure the bit enters the wood cleanly without tearing the wood fibres, the main cutter then follows to remove the material quickly to avoid the build-up of heat. The bits feature a threaded centre point which pulls the bit through the wood meaning minimal force is needed for the bit to work at full capacity. The deep flute allows fast chip removal to prevent clogging when drilling deeper holes. 

The auger bits are made from high carbon steel which has been hardened to ensure a long service life and give the bits impressive cutting properties when compared to traditional steel auger bits. The bits have been fully ground to give precise concentricity to ensure a highly accurate hole. A hexagonal shaft ensures a secure hold that will not slip inside the chuck during use. Auger bits are normally used at low speeds between 700 and 2000rpm to prevent the wood from scorching. The speed depends on size, with the larger diameter bits being used at lower speeds.

These bits are certified to ensure the dimensional accuracy of the hole and the set contains 6mm, 14mm, 18mm, and 22mm. The overall length of the bits is 460mm with a flute length of 370mm. ©
