Milwaukee Tool 48-17-6014 Core Bit Extension 6 in

Product Description

The MILWAUKEE TOOL 48-17-6014 is a 1-1/4-7 threaded core bit extension designed to increase drilling depth when working with 1-1/4 inch core bits. With a 6-inch overall length (OAL), this extension threads directly onto compatible drill shanks to give trades more reach on deep-bore applications through concrete, masonry, or similar materials. The 1-1/4-7 thread pattern is a standard designation for core drill tooling, making this a straightforward addition to a professional core drilling setup. At 3.8 pounds, it is built for durability under the demands of rotary and core drilling work.

This extension is suited for use in residential and commercial construction environments where core drilling is required through concrete floors, walls, foundation sections, or masonry block. Typical applications include creating penetrations for plumbing, conduit, HVAC ductwork, and mechanical sleeves. It is compatible with threaded drill shanks that accept the 1-1/4-7 thread standard, and it is designed to work with 1-1/4 inch core bits. Electricians, plumbers, and general contractors running core drills on job sites will find this extension useful for reaching depth in thick structural assemblies.

Installation Notes

Installation is typically performed by a licensed tradesperson familiar with core drilling equipment. Before attaching or removing any extension, power down the core drill and verify the machine is fully de-energized or disconnected from its power source. Thread the extension onto the drill shank by hand first to confirm engagement, then secure according to the drill manufacturer's guidance. Inspect threads on both the extension and core bit before each use to avoid cross-threading or connection failure under load.
