Application Guidance

This bit is intended for use with right-angle drills and heavy-duty power drills capable of delivering consistent torque. Suitable for framing, rough-in plumbing, and electrical conduit installation. Avoid use in non-wood materials or rotary hammer modes. Replace feed screws as needed to maintain optimal feed rate and control.

Contractor Use Notes

The Lenox 33256 is designed for repeated daily use in construction environments. Its cutting geometry is optimized for speed and chip evacuation, while the bi-metal body provides longevity under intermittent nail impact. For best results, maintain consistent pressure and let the feed screw advance the bit without over-driving.
