The drill bit is made of high quality HSG steel. The unique step-hardening gives the highest hardness of the cutting edge and drill shank, and also contributes to increased resistance to fracture. The drill has a cruciform sharpening angle of 135 degrees, accuracy class A1, which ensures low runout and allows you to produce accurate and uniform holes. Thanks to the alloy with the addition of 6% Tungsten and 5% Molybdenum, the drill is able to withstand high temperatures, and 4% Chrome and 2% Vanadium in the composition prevent drill corrosion, prolonging the life of the product. Designed for drilling holes in carbon and alloy steels, gray and ductile irons, non-ferrous metals and plastics.
