Drill made from high-speed steel (4241) with a hardness of 62°HRc (+/-2°) and a point angle of 118°. With straight cutting without edge correction and suitable for manual sharpening.

Right-hand spiral drill with type N thread, heat-raised in cylinders, with high elasticity and torsion resistance, polished cuts. Diameter tolerance h8. Cylindrical shank with reduced shank diameter at ø13.0mm.

The surface of the drill is covered with an oxide layer, providing a low friction coefficient and reducing the risk of chip adhesion to the drill, increasing drilling efficiency. Intended for general use, for machining structural steels, low alloy and alloy with strength up to Rm < 600MPa, graphite, non-ferrous metals, and hard plastics.

Complies with DIN-338 standard. To improve the quality of the hole, it is recommended to use a suitable coolant, depending on the type of material being drilled. With proper use of coolant, the drill's lifespan increases fourfold. Recommended coolants: drill emulsion, lubricant-coolant oil, ester oil.
