  • Superior quality car
• 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
