MX4™ 4-Cutter SDS-Plus Rotary Hammer-Drill Bit 3/16 in. x 4 in. x 6 in.

Milwaukeeᴹᴰ MX4™ 4-Cutter SDS-Plus Rotary Hammer Bits provide up to 4x life in rebar and up to 20% more holes per charge in cordless rotary hammers. Enhanced rebar guards and a 90° 4-cutter head design deliver increased life and durability in hard aggregate and rebar. The breaking tip pulverizes material more effectively resulting in faster drilling speeds. The variable flute allows for maximum debris extraction resulting in up to 20% more holes per charge in cordless rotary hammers, while making this a highly durable bit in corded and cordless rotary hammers. In addition, the MX4™ features a centering tip for exact spot drilling, a wear mark indicator that shows when the bit no longer meets ANSI diameter requirements, and a reinforced flute for durability and minimized vibrations. The increased life and efficiency of the MX4™ 4-cutter bit line provides the ideal solution in general concrete and reinforced concrete for cordless and corded rotary hammer users.
