Drill fi 18,75 with cylindrical shank

Drill 18,75 mm HSS. High-performance cylindrical twist drill bit for drilling through-holes and blind holes in P1.2 P1.3 grade materials (metals, metal alloys, non-alloy steels, non-ferrous metals). The drills have 2 central blades, a tip angle of 118 degrees, specially ground cutting edges and spiral grooves for efficient chip removal up the hole. The NWKa drills we offer are manufactured from modern HSS high-speed steel. Its high cutting properties significantly increase drilling efficiency, as well as improve the precision of the holes. In addition, the drills are resistant to harsh cutting conditions and their blades are resistant to mechanical damage (fractures, cracks, chipping, breakage). Drill bits for metal 18,75 mm are also characterized by greater hardness and durability against abrasion under the influence of high temperatures generated when drilling at high speed. Recommended for conventional and computer-controlled machine tools - CNC.
