Solid carbide HPC pilot drill Garant with 4 cooling channels Cutting chisel edge with high centring accuracy - due to special point geometry and strong core. High roundness and alignment accuracy of the deep hole, thanks to 4 guide chamfers. Outstanding chip evacuation due to 4 internal cooling channels from 0 3.8 mm. Up to 3.7 mm 0 with 2 internal cooling channels. Version Solid carbide DIN 6537 6xD p6 I40‘ DIN I 6535 HAHBHE 25 bar With 140° point angle and special j6 cutting edge tolerance for optimum generation of a pilot hole. Effective length For the exact L/D ratio please refer to the respective 0 and flute length.
