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.

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.

The MILWAUKEE® SDS Plus Rebar Cutters are the toughest in rebar, delivering up to 3x life in rebar compared to competitive rebar cutters. These bits, designed with precision ground carbide for rebar only drilling, provide up to 10x faster drilling speeds in rebar vs. 4-cutter drill bits. Milwaukee SDS Plus Rebar Cutters are equipped with HAMMER GUARD™ protective shanks, preventing carbide teeth destruction from accidental use in rotary hammer mode, saving time and money. Deep debris channels provide the fastest rebar shard removal while double ejection slots allow for easy rebar slug removal. Available in sizes 3/8” – 1-1/2”, Milwaukee SDS Plus Rebar Cutters are the optimal solution for drilling embedded rebar for corded and cordless SDS Plus rotary hammers. For use in rebar only.
