Hoffmann Group 47 Solid carbide DIN 6537 S3 6xD p6 h6 40' DIN 6535 HAHBHE HPC 25 bar 4aBM id Solid carbide HPC pilot drill with 4 cooling channels Cutting chisel edge with high centring accuracy due to strong core and special point geometry. High roundness and alignment accuracy of the deep hole, thanks to 4 guide chamfers. Outstanding chip evacuation due to 4 internal cooling channels from 0 3.8 mm. Up to 3.7 mm 0 with 2 internal cooling channels. With 140° point angle and special j6 cutting edge tolerance for optimum generation of a pilot hole. Effective length: For the exact L/D ratio please refer to the respective 0 and flute length Note: For deep-hole drilling deeper than 12xD a pilot hole is recommended, and for deep-hole drilling from 20xD to 30xD it is essential. The generation of a pilot hole always improves process reliability. Form HB and HE supplied at the same price as HA. n l Form HB: order with No. 122738. r-m Form HE: order with No. 122736 + 129100HE.
