Version :
Spiral fluted, with 6 guide chamfers and internal cooling channels. New generation of high performance pilot drills in the HPC range. With 140° point angle and special p6 cutting edge tolerance for optimum generation of a pilot hole. High alignment accuracy and roundness of the pilot hole.
Note :
Flute length LC = L2 + 1.5 × DC. For deep-hole drilling deeper than 16×D a pilot hole is recommended, and for deep-hole drilling from 20×D to 30×D it is essential. The generation of a pilot hole improves process reliability. Form HB and HE supplied at the same price as HA. Form HB: order with No. 122608. Form HE: order with No. 122606 + 129100HE.
