Irwin 3046013 Speedbor Max Self Feed Bit 2-9/16 in

Product Description

The IRWIN INDUSTRIAL TOOL CO 3046013 is a 2-9/16 inch diameter Speedbor Max self feed drill bit engineered for cutting large diameter holes through wood framing and structural lumber. Forged in one piece from high carbon steel, this bit is built to withstand tough drilling conditions without flex or fatigue. The 7/16 inch hex quick-change impact shank fits any 1/2 inch or larger drill and is also compatible with 7/16 inch hex impact wrench drills. An aggressive screw pitch pulls the bit through material efficiently, while the precision milled shank eliminates runout and wobble for cleaner, more consistent holes.

This self feed bit is used by plumbers, electricians, HVAC installers, and general contractors who need to bore large holes through wood framing, plates, and joists for pipe and conduit routing. Its cutting geometry delivers three times the cutting area and edges compared to standard self feed bits, making it a practical choice for high-volume rough-in work on residential and light commercial job sites where speed and hole quality both matter.

Key Features

• 2-9/16 inch cutting diameter for large bore applications in wood
• One-piece high carbon steel construction for maximum strength under load
• Three times the cutting area and edges versus standard self feed bits
• 7/16 inch hex quick-change shank fits 1/2 inch or larger drills and 7/16 inch hex impact wrench drills
• Aggressive screw pitch for fast, self-feeding material penetration
• Precision milled shank eliminates runout and wobble
• Designed for pipe and conduit system rough-in work

Compatibility

Fits any 1/2 inch or larger drill with a standard chuck, and any drill or driver equipped with a 7/16 inch hex impact wrench interface. Designed for drilling large diameter holes in wood for pipe and conduit systems.

Installation Notes

This bit is installed and used by plumbers, electricians, and HVAC rough-in crews working with standard or impact-rated drills. Before drilling near existing infrastructure, verify no energized wiring, plumbing, or structural fasteners are in the path. Use appropriate PPE including eye protection when operating self feed bits at high speeds. Allow the aggressive screw pitch to feed at its natural rate without forcing the tool, which can reduce bit wear and improve hole quality.
