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. Note: Flute length LC = L2 + 1.5 × DC. Form HB and HE supplied at the same price as HA. Form HB: order with No. 122772. Form HE: order with No. 122773.
