Milwaukee® M12™ 48-20-7438 2-Cutter Rotary Hammer Drill Bit, 1/4 in Drill Bit, 25/64 in SDS-Plus Shank, 18 in D Cutting, Carbide Cutting Edge, 20 in OAL
Milwaukee® M/2™ 2-cutter SDS Plus rotary hammer drill bits are the most durable 2-cutter bits with up to 20% more holes per charge in cordless rotary hammers. The enhanced rebar guards provide increased durability in hard aggregate and rebar. 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 hammer while making it a very durable bit in corded and cordless rotary hammers. Additionally, M/2™ 2-cutter 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. The increased life and efficiency of the M/2™ 2-cutter drill bit line provides the ideal solution in general concrete for cordless and corded rotary hammer users.
