Milwaukee® 48-20-3972 4-Cutter Rotary Hammer Drill Bit, 1-1/4 in Drill Bit, 45/64 in SDS-Max Shank, 18 in D Cutting, Carbide Cutting Edge, 23 in OAL
The MILWAUKEE® MX4™ 4-Cutter SDS MAX Rotary Hammer Drill Bits with solid head carbide deliver up to 5x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. Milwaukee designed their MX4™ 4-Cutter bits with sharp centering tips for exact spot drilling in concrete. The integrated 4-cutter design prevents lock-up in rebar, reducing downtime. Optimized flutes remove dust faster, reducing heat and delivering up to 15% more holes per battery charge. The wear mark indicator on each drill bit shows you when they no longer meet the ANSI requirement. These MILWAUKEE® MX4™ 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications.

Milwaukee® 48-20-8041 M/2™ 2-Cutter Rotary Hammer Drill Bit, 8 mm Drill Bit, Spear Cutting, 0.315 in SDS-Plus Shank, 250 mm D Cutting, Carbide Cutting Edge, 310 mm 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™ 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.

Milwaukee® 48-20-4137 2-Cutter Rotary Hammer Drill Bit, 1-3/8 in Drill Bit, 3/4 in Spline Shank, 10 in D Cutting, Carbide Cutting Edge, 16 in OAL
Two cutter spline bits have a series of 12 spline that slide into an equal but opposite set of spline in the drive system of the spline drive hammer. This positive engagement of spline to spline allows maximum transmission of energy from the hammer to the bit. Superior quality Carbide nibs are vacuum brazed to a heat treated steel body resulting in two cutting edges which pulverize the concrete as the bit turns and pounds the work surface. Available from 3/8 in. to 1-1/2 in. diameters as well as metric diameters. One per package.
