Hoffmann Group 47 Solid carbide I'vMvfl Standard fg6 A h5 II / HOEO DIN6535 35 hahbhe 40 bar HPC 4asat M Solid carbide HPC deep hole drill 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 fg6 cutting edge tolerance for optimum generation of deep holes. High round ness and alignment accuracy of the deep hole. Note: To achieve good process reliability with 40xD and 50xD deep-hole drills it is absolutely essential to drill 6xD pilot hole with a No. 122736 and a 20xD co-pilot hole with a No. 123691 co-pilot drill. The generation of a pi lot hole improves process reliability. See also page 114/115. See www.hoffmann-group.com for further details.

It ensures process reliability and reduces the costs. The minimum drilling depth (see table) depends on the desired deep hole depth. The use of a pilot hole eases the subsequent deep hole drilling operation and improves the life of the deep hole drill.
