1-1/8" Standard Selfeed drill bits, Clean Holes, Accurate Drilling

Milwaukee 48-25-1122 – 1-1/8" Selfeed Drill Bit for High-Speed Wood Drilling

The Milwaukee 48-25-1122 Selfeed Drill Bit is engineered for producing clean, fast holes in wood, making it ideal for rough-in work involving pipe, conduit, and other mechanical penetrations. Designed for heavy-duty applications, it delivers consistent performance in repetitive drilling scenarios commonly encountered in residential and commercial construction.

Professional Features

• Size: 1-1/8 inch nominal diameter
• Feed Screw Tip: Self-feeding screw design assists with material penetration and control during drilling
• Resharpenable Blade: Allows for multiple sharpening cycles to extend tool life
• Hex Shank: 7/16" impact-rated shank provides secure grip and compatibility with standard and right-angle drills
• Included Components: Ships with two removable feed screws for replacement in the field
• Finish: Coated with rust inhibitor to minimize corrosion during storage and use

Performance Applications

This self-feed bit is optimized for use in wood and engineered wood products. It is particularly suited for boring through wall studs, joists, and subfloor during plumbing, electrical, and HVAC rough-in installations. The bit's aggressive cutting edge and center screw reduce effort required by the operator and help maintain accuracy in repeated cuts.

Compatibility

• Tool Type: Designed for use with corded or cordless right-angle drills, spade handle drills, and drill drivers
• Material Suitability: Softwood, hardwood, and engineered wood substrates

Usage Guidance

Operators should verify tool compatibility and inspect feed screws and cutting edges prior to use. Routine sharpening of the bit edge and proper drilling technique will ensure consistent results across multiple installations. Always follow safety protocols when using self-feeding bits due to their rapid feed rate and torque demands.

Key Advantages

• Clean Entry and Exit: Optimized blade geometry reduces blowout on exit
• Jobsite Durability: Rugged construction designed to withstand repeated drilling in high-volume environments
• Replaceable Components: Interchangeable feed screws extend operational lifespan
• Efficient Chip Ejection: Open body design helps clear chips during operation

The Milwaukee 48-25-1122 is a proven solution for high-speed, high-volume drilling in wood substrates. Its durability and serviceability make it a practical choice for contractors requiring precision and efficiency on demanding jobs.
