Milwaukee® MX4™ 4-Cutter SDS-Plus rotary hammer drill bits provide up to 4x life in rebar and up to 20% more holes per charge in cordless rotary hammers.

Breaker point pulverize the material more effectively resulting in faster drilling speeds. The variable flute allows for maximum debris extraction leading to up 20% more holes per charge in cordless rotary hammers while making it a very durable bit in corded and cordless rotary hammers. Additionally, MX4™ features a centering tip for exact spot drilling, wear mark indicator indicating when the bit no longer meets ANSI diameter requirements, and a reinforced flute for durability and minimized vibration.
