Hammer Drill Bits

Milwaukee®’s Spline 4-cutter rotary hammer drill bits feature a 4-cutter 4 x 90° tip geometry to avoid lock up in rebar, patented rebar chamfers for increased durability, and a high volume flute for fast debris removal. Used for drilling holes in brick, block, concrete, and reinforced concrete.

Four cutter Spline bits have a series of 13 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. 4 cutter style bits are also available in metric (from 16 mm to 38 mm). One per package.

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.
