Description
Version:
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 ⌀ 3.8 mm. Up to 3.7 mm ⌀ with 2 internal cooling channels. Straight major cutting edges with honed edges and special flute profile for short chips, even on long chipping materials.
Note:
Flute length LC = L2 + 1.5 × DC.
