Masonry Drill Bit 3/16 in x 4 in x 6 in SDS-Plus MX4™

Milwaukee® MX4™ 4-Cutter SDS-Plus Rotary Hammer Bits provide up to 4X longer 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 provide 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, leading to up to 20% more holes per charge in cordless rotary hammers, while also making this bit a very durable tool in corded and cordless rotary hammers. In addition, the MX4™ features a centering tip for exact spot drilling, a wear mark indicator letting you know 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.
