Beschreibung
Version:
Tool specially matched to drilling holes without through-coolant. Concave major cutting edges and a special flute profile ensure a good chip evacuation. The sturdy cutter geometry with special point geometry and 4 cutting edges ensures drilling with good process reliability. A wide range of applications in steel materials thanks to a combination of tough ultra-fine grain carbide and extremely wear-resistant and heat-resistant coating.
