Solid carbide HPC deep hole drill Garant Spiral fluted, with 4 guide chamfers and internal cooling channels. New generation of high performance deep hole drills in the HPC range. With 135° point angle and special h7 cutting edge tolerance for optimum generation of a deep hole. High roundness and alignment accuracy of the deep hole. 20xD 16xD 123688 123690 Note For process reliability when using the 16xD deep-hole drill, an initial centre drilling or4xD pilot drilling operation with pilot drill No. 122736 is necessary. For deep holes of 20xD, a 6xD pilot hole with pilot drill No. 122736 is absolutely essential. The generation of a pilot hole increases process reliability. See pages 92 / 93. See for further details Versions with HB and HE shank available without surcharge. Form HB add product code No. 129100HB. Form HE add product code No. 129100HE.
