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.

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.
