Precision twist drill, cylindrical, extra-long, type NWKp, with a cross section of 2.5 mm, designed for high-performance drilling of very deep through-holes and blind holes. The NWKp drill bits we offer, are in accordance with the dimensional standard DIN 1869, made of modern high-grade HSS. The addition of cobalt makes the drills harder and more resistant to harsh cutting conditions. The fi 2.5 cobalt long metal drills are suitable for drilling holes in very hard alloy steels, stainless steels, heat-resistant and heat-resistant steels, gray and ductile iron, as well as cast steel, metal alloys and other hard materials. HSS allows much higher cutting effects, primarily better accuracy and precision. NWKp drills of this type are also characterized by higher hardness and durability against abrasion under the influence of high temperatures (up to 670 degrees) created when drilling at high speed.
