1-3/8" Standard Selfeed drill bits, Clean Holes, Accurate Drilling

Milwaukee 48-25-1372 1-3/8" Selfeed Bit – Designed for High-Efficiency Wood Boring

The Milwaukee 48-25-1372 Selfeed Drill Bit is engineered for repetitive drilling in wood, making it a reliable choice for rough-in work in plumbing, electrical, and HVAC applications. Designed for use with drills equipped with a 7/16" hex quick-change chuck, this bit provides aggressive cutting action and precise results in dimensional lumber, engineered wood, and laminated materials.

Product Features

• Bit Diameter: 1-3/8 inch – Ideal for boring conduit and pipe clearance holes
• Shank Type: 7/16" hex shank for enhanced grip and reduced slippage
• Feed Screw: Includes two replaceable feed screws to maintain consistent pull-through during operation
• Reusability: Cutting edges are resharpenable to extend tool life and reduce replacement costs
• Protective Coating: Factory-applied rust inhibitor resists corrosion in high-humidity or damp jobsite conditions

Application Overview

Designed for use with corded or cordless drills, the Selfeed bit is optimized for boring clean, flat-bottomed holes at high speed. It excels in framing applications where repeated, uniform holes are needed—such as in wall studs, joists, or plates for running water lines or conduit.

Usage Guidelines

• Use with a drill capable of supporting large diameter bit loads and slow RPM
• Maintain cutting edges and replace feed screw as needed to sustain performance
• Clear chips frequently to avoid binding during continuous boring

Key Advantages for Trades

• Contractor-Grade Durability – Built to handle repetitive drilling in framing lumber
• Efficient Boring – Self-feeding tip minimizes applied pressure, reducing user fatigue
• Serviceable Design – Resharpenable blades and replaceable feed screw support extended use
