Drills with a short cylindrical shape for metal, according to DIN 338, type N, with an edge angle of 118°. Made from HSS-G, processed and ground with a left-hand cutting edge. Helix angle 20-30°. Diameter tolerance h8. From 2 mm with additional polishing on the support surface and reduced cutting edge, according to DIN 1412 C, for easier cutting and decreased cutting force, as well as faster drilling.
Designed for drilling in steels, cast irons (non-alloyed and alloyed), with Rm 800 N/mm², as well as heat-treated steels with Rm 1100 N/mm². Drilling in cast irons, ductile cast irons, elastic cast irons cast under pressure, and non-ferrous materials (aluminum, copper, and bronze alloys), plastics, and various compressed materials (not suitable for powder metallurgy or ceramic-metal composites). Recommended for use in drilling machines, fixed and permanent setups, and occasionally in portable electric or pneumatic drilling machines.
