12mm Diameter Lewis Wood Augers with a 11.5mm Hex Shank
The Auger bits have one taper tap, one main cutting edge as well as a crest of thread, which is particularly suitable for soft wood and European hard wood. The mode of operation is similar to the Forstner Bit: First the taper tap will pre-cut the wood fibre of the outer cross ring, then the main cutting edge will do the main work.
The Augers are ideal for carpenters, automatic carpentry machines and anywhere where people need to drill deep holes in wood. The shafts are manufactured with a hexagonal shank, in order to avoid the shaft twisting in the machine (from diameter 10mm).
Auger bits can be custom made to your requirements with up to 2500mm length and 80mm diameter a feasible option.
Our Lewis pattern are characterized by a milled helix. This kind of helix warrants the highest bending stiffness at maximum chip space. Therefore our Augers Bits temove the wood chips without any problems.
