Irwin 3041009 Speedbor Max Spade Bit 1-1/4x6 in

Product Description

The IRWIN INDUSTRIAL TOOL CO 3041009 is a Speedbor Max spade-style wood boring bit designed for fast, clean drilling in wood and wood composites. Measuring 1-1/4 inches in diameter and 6 inches in length, this standard-length bit features a tri-flute body geometry that accelerates chip ejection and keeps the flutes clear during deep passes. The full screw tip is self-feeding, pulling the bit through the workpiece without requiring excessive forward pressure. Cutting spurs are ground with three cutting edges each, extending durability in repetitive drilling applications. The grooved hex shank seats firmly in standard drill chucks and bit extensions, preventing rotation or slippage under load. Sold as a package of 3 bits.

This bit is suited for residential and light commercial construction, rough-in work, and trade applications where drilling clean, oversized holes through framing lumber, plates, joists, and similar structural wood is required. Electricians, plumbers, and HVAC technicians commonly use spade bits of this diameter when running conduit, pipe, or duct penetrations through wood framing. The 6-inch length gives enough reach for standard framing members without requiring an extension for most single-stud passes. The tri-flute design makes it particularly effective in cordless drill drivers where maintaining bit speed through dense material is a concern.

Key Features

• Tri-flute design accelerates chip ejection and reduces clogging in deep holes
• Three cutting edges per spur for increased durability in repetitive use
• Full screw tip is self-feeding, reducing forward pressure required during drilling
• Grooved hex shank prevents slipping in drill chucks and bit extensions
• Compatible with all standard 1/4-inch quick-change chuck systems
• Package includes 3 bits for job-site redundancy

Compatibility

Fits all standard 1/4-inch quick-change chucks and standard drill chuck configurations. Compatible with corded and cordless drill drivers accepting a grooved hex shank. Designed as a direct-use spade bit for wood boring applications in standard drill platforms.

Installation Notes

Installation and use should be performed by qualified trade professionals or experienced operators familiar with rotary drilling tools. Secure the workpiece before drilling and ensure the chuck is fully tightened onto the grooved hex shank before applying power. When drilling through framing near electrical conductors, gas lines, or plumbing, verify line locations before drilling to avoid contact. Eye and hearing protection should be worn during operation per standard jobsite safety practice.
