Drill 7,4 mm on Morse taper with fin

Drill fi 7,4 mm with Morse taper shank for steel, type NWKc, in accordance with DIN 345. Designed for drilling through-holes and blind holes with a diameter of 7,4 mm. The drill has strong ground cutting edges, spiral grooves for chip evacuation, and center blades with an angle of 118 degrees. The drill is manufactured entirely from special HSS (High Speed Steel). It is a drill bit designed for industrial drilling of holes in hard materials classified as P1.2 - 1.3. The HSS drill bit is characterized by enhanced cutting capabilities. It allows high-performance machining (at high speed) as well as very accurate machining. The holes made are axial along the entire length and have a very low degree of roughness. The design of the drill allows drilling in metals, unalloyed steels, non-ferrous metals and metal alloys.The 7.4 metal drill bits are suitable for conventional and CNC computer-controlled machine tools
