Milwaukee 48-20-7663 8 PC MX4 4-Cutter SDS Plus Drill Bit Kit

The Milwaukee 48-20-7663 SDS Plus Drill Bit Kit features MX4 4-Cutter drill bits engineered for demanding concrete and masonry applications. With solid head carbide construction and specialized rebar guards, these bits are designed to deliver extended service life when drilling in concrete containing rebar and hard aggregate.

The 4-cutter head design helps prevent lock-up when encountering rebar, while the sharp centering tip provides precise spot drilling in concrete and metal decking. Variable flutes are designed to remove dust efficiently, helping reduce heat buildup and delivering up to 20% more holes per battery charge when used with compatible cordless rotary hammers.

Each drill bit includes a wear mark indicator that helps identify when the bit has reached the end of its service life and no longer meets the ANSI requirement. The bits meet ANSI B212.15 requirements for common anchors and are designed to fit SDS Plus rotary hammers.

The Milwaukee 48-20-7663 kit includes eight MX4 4-Cutter SDS Plus rotary hammer drill bits in commonly used sizes from 5/32-inch to 1/2-inch. The set comes packaged in a medium, double-sided hard case designed for use with the Milwaukee PACKOUT Storage System, helping keep drill bits organized and accessible on the jobsite.
