Description
Version:
Straight major cutting edges and a special flute profile ensure a good chip evacuation. The robust cutter geometry ensures high-performance drilling with good process reliability.
A wide range of applications in steel materials thanks to a combination of tough ultra-fine grain carbide and an extremely wear-resistant coating.
Up to ⌀ 1.9 with 4 facets, from ⌀ 2 with relieved cone.
Cutting chisel edge with high centring accuracy due to strong core and special point geometry. Straight major cutting edges with slightly honed edges and special flute profile produce short chips.
