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 |
Four cutter 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 |
