Milwaukee MX4 SDS Plus Masonry Drill Bit

The Milwaukee MX4 SDS Plus Masonry Drill Bit is engineered for professional tradespeople who demand precision, speed, and durability on site. Featuring a symmetrical 4 cutter geometry (4 x 90°), these bits are designed to produce perfect round holes — ideal for anchor fitting in concrete, brick, and masonry.

High volume flutes channel dust and debris away efficiently during drilling, while a precision centering tip ensures quick, accurate starting without slipping. Enhanced rebar guards provide improved resistance when striking rebar, and four breaker points pulverise material for faster penetration. The dual-zone flute design — thin at the tip for maximum extraction, thick at the base for stability — delivers outstanding performance across demanding commercial applications.

Available in diameters from 5mm to 30mm and lengths from 110mm to 1000mm, with single, 10-pack, and 50-pack quantities to suit every job requirement.
