Solid carbide high performance drill, Whistle-Notch shank DIN 6535 HE TiN 3 mm HOLEX
Strong core and special point geometry ensure the cutting chisel edges maintain high self-centring accuracy. Straight cutting edges with slight edge hone and a special flute profile produce short chips.
Note:
Flute length LC = L2 + 1.5 × DC. For process reliability when using the 12×D deep-hole drill, an initial centre drilling with No. 121068 – 121130 or 3×D pilot drilling operation with No. 122736 is necessary.
