Masonry Drill Bit 1/2 in x 16 in x 18 in SDS-Plus MX4™

Milwaukee® 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 MX4™’s 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 also making this a very durable bit in corded and cordless rotary hammers. Additionally, the MX4™ features a centering tip for exact spot drilling, a wear mark indicator showing when the bit no longer meets ANSI diameter requirements, and a reinforced flute for durability and minimized vibration. 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.
