Bore clean, large-diameter holes in wood framing with this DEWALT heavy-duty self-feed bit. The self-feeding screw tip pulls the bit through the material at a steady rate, while an aggressive spur scores the hole perimeter for fast, clean penetration.

• 2-1/8" cutting diameter
• Self-feeding screw tip pulls the bit through the work, reducing operator push
• Aggressive spur for fast material penetration
• Optimized cutting geometry for long bit life
• Open-tooth design for easy re-sharpening
• 7/16" ball groove shank for quick-change applications
• For wood only - check the work for nails before drilling

Ideal for plumbing, electrical and HVAC rough-in, where holes for pipes, cables and ductwork have to run through studs, joists and headers.
