| 5/8 IN Diameter, 2-Cutter Head; Spline Shank; Drilling Depth 10 IN; Overall Length 16 IN |
| 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 |
| 11 in useable length |
