High roundness and alignment accuracy of the deep hole. 122736 is necessary. With 135 Deg point angle and special h7 cutting edge tolerance for optimum generation of a deep hole. The generation of a pilot hole improves process reliability. Spiral fluted, with 4 guide chamfers and internal cooling channels. 121068 - 121121 or 4xD pilot drilling operation with pilot drill No. 122736 is absolutely essential. For deep holes greater than 20xD, a pilot hole to the maximum drilling depth with pilot drill No. New generation of high performance deep hole drills in the HPC range. Note: For process reliability when using the 16xD deep hole drill, an initial Center drilling with No.
