Four 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 four cutting edges which pulverize the concrete as the bit turns and pounds the work surface. Available from 5/8 in. to 1-1/2 in. diameters (also available in metric from 16 mm to 38 mm).

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® 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.
