- Milwaukee®'s Spline 2-Cutter Rotary Hammer drill bits are used for drilling intro brick, block, and concrete
- Brazing formula optimizes drilling for up to 20% longer life
- Unique flute geometry provides efficient dust removal
- Centering point and 4-cutter design provide accurate and precise round holes
- Two 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 two cutting edges which pulverize the concrete as the bit turns and pounds the work surface
- 17 in useable length
