Description
Helical fluted, with 4 guide chamfers and internal coolant holes. New generation of high performance co-pilot drills in the HPC range. With 138 Deg point angle and special j6 cutting edge tolerance for optimum generation of a co-pilot hole. High roundness and alignment accuracy of the co-pilot hole. Note: Flute length LC = L2 + 1.5 x DC. To achieve good process reliability with 40xD and 50xD deep hole drills, it is absolutely essential to drill a pilot hole to the maximum drilling depth with a pilot drill No. 122736 and a 20xD co-pilot hole with a co-pilot drill No. 123691. The generation of a pilot hole improves process reliability.
