Product Description
The Bohrcraft LEWIS heavy-duty auger wood drill bit 8 x 460 mm (working length 360 mm) is a professional framing and carpentry bit engineered for deep-hole boring in timbers and log structures. The self-feeding threaded screw tip draws the bit smoothly into the timber with minimal operator push. Featuring a single main cutting edge with spur (Z1) and an innovative "step-tip" geometry, it delivers clean chip evacuation even in wet, green, or resinous timber without clogging. The hexagonal shank (7.2 mm) prevents chuck slip under heavy torque loads.
