Drills made of high-speed steel (4241) with a hardness of 62°HRc (+/-2°), a point angle of 118°, straight cut without chamfer correction, suitable for manual sharpening.
Diameter tolerance h8.
Right-hand twist drill bits with an N-type helix, hot-rolled on forging rolls, with high flexibility and torsion resistance, ground blades.
Cylindrical shanks corresponding to the diameter of the drill bits.
The surface of the drills is covered with an oxide layer, which provides a low coefficient of friction, reduces the risk of chips sticking to the drills and increases drilling efficiency.
Designed for general use, for machining alloy and carbon steels up to 250Bhn hardness, gray cast iron, non-ferrous metals and hardened plastics.
