The ROK 7/8" x 18" Auger Bit is a professional-grade wood boring bit engineered for fast, clean, and deep hole drilling in framing lumber, engineered wood, and timber. The self-feed screw point draws the bit through wood automatically with each rotation — reducing the pressure required from the operator and delivering fast, consistent boring without bit walking or repositioning. The edge-cutting spur scores the perimeter of the hole before the main bit removes material, producing smooth, splinter-free entry and exit holes. The spiral flute design efficiently evacuates chips and sawdust from deep holes to prevent clogging and overheating, maintaining cutting speed and accuracy throughout the bore. At 18" in overall length, this bit drills deep passages for wiring, plumbing, and structural applications without requiring an extension. The 7/16" hex shank provides a secure, wobble-free connection in standard drill chucks and quick-change systems. Made from high-quality carbon alloy steel for long-lasting sharpness and durability.
