Milwaukee 48-27-1121 Flat Boring Bit 1-1/8 X 6 Inches

Product Description

The MILWAUKEE 48-27-1121 is a flat boring bit designed to drill clean, fast holes at any angle in wood, plastic, plywood, and Formica. Measuring 1-1/8 inches in diameter and 6 inches in length, it provides a full 6 inches of drilling depth per pass. The bit is constructed from heat-treated high carbon steel, allowing the drill point and cutting edges to be resharpened multiple times, extending service life and reducing replacement costs. This is a practical, field-proven boring tool for electricians, plumbers, and carpenters who need reliable performance across a range of common building materials.

This flat boring bit is suited for residential and light commercial applications where accurate, clean through-holes are required in framing lumber, plywood subflooring, cabinetry panels, and plastic sheet goods. It performs at any drilling angle, making it useful for both straight-through and angled boring scenarios. When greater depth is needed, the bit is compatible with a 12-inch extension (MPN: 48-28-3350) to reach into deep cavities or through thick assemblies.

Key Features

• 1-1/8-inch diameter bore for consistent, clean hole sizing
• 6-inch drilling depth covers most standard framing and panel applications
• Heat-treated high carbon steel construction for durability and resharpening capability
• Compatible with 12-inch extension (48-28-3350) for deep-hole drilling
• Cuts effectively in wood, plastic, plywood, and Formica at any angle

Compatibility

Compatible with the MILWAUKEE 48-28-3350 12-inch extension for extended deep-hole drilling. Designed as a standard flat boring bit for use with any drill or right-angle drill accepting a standard spade-bit shank.

Installation Notes

This bit is typically used by electricians, plumbers, and carpenters during rough-in work requiring holes through framing or panels. Secure the workpiece before drilling and operate at a speed appropriate for the material and bit diameter. Inspect and resharpen the cutting edges regularly to maintain clean hole quality. Always follow applicable local codes and job-site safety requirements when boring through structural members.
