Description

Version:

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. 121068121130 or 3×D pilot drilling operation with No. 122736 is necessary.
