Milwaukee 48-27-1251 Flat Boring Bit 1-1/4 X 6 in

Product Description

The MILWAUKEE 48-27-1251 is a flat boring bit designed for drilling clean, precise holes in wood, plastic, plywood, and laminate materials. Built from heat-treated high carbon steel, the bit delivers consistent cutting performance and can be resharpened at the drill point and cutting edge, extending service life and reducing replacement costs. With a 6-inch drilling depth, this bit suits a wide range of rough-in and finish boring tasks performed by electricians, plumbers, and carpenters working through framing, subflooring, and similar substrates.

This flat boring bit is suited for residential and light commercial applications where clean through-holes are required at standard or angled entry points. It performs in wood framing, plywood sheathing, plastic panels, and laminate surfaces. The bit is a practical choice for trade professionals drilling penetrations for pipe, conduit, or wire routing during rough-in phases. Compatible extension accessories allow for deep-hole drilling beyond the standard reach when working through thicker assemblies.

Key Features

• Heat-treated high carbon steel construction for durability and resharpening capability
• 6-inch drilling depth suits most standard framing and panel applications
• Cuts cleanly at any angle in wood, plastic, plywood, and laminate
• Drill point and cutting edge are field-resharpenable, reducing long-term tooling cost
• Compatible with 12-inch extension 48-28-3350 for extended deep-hole drilling

Compatibility

Compatible with the MILWAUKEE 48-28-3350 12-inch extension for extended deep-hole drilling applications. Designed as an OEM-style flat boring bit for use with standard hex or spade-style bit chucks on corded and cordless drills.

Installation Notes

Installation and use of this bit is typically performed by licensed electricians, plumbers, and general contractors during rough-in phases of construction. Ensure the drill is powered off and the chuck is fully secured before inserting or removing the bit. When drilling at angles or through multiple layers, reduce feed pressure near breakthrough to minimize tearout. Follow applicable NEC or IPC clearance requirements when sizing penetrations for conduit or pipe routing.
