Drill 28.25 mm on Morse taper with fin

Drill fi 28,25 mm with Morse taper shank for steel, designed for professional drilling of through-holes and blind holes with a diameter of 28,25 mm. This is an NWKc drill bit, made according to the dimensional standard DIN 345, from special HSS (High Speed Steel). Thanks to its properties, the tools are characterized by higher drilling parameters. They make it possible to achieve in higher machining efficiency and better drilling accuracy. The holes produced are axial along the entire length and with low roughness. The 28.25 HSS metal drill bits in question have strong cutting edges that are insensitive to strong impacts and lateral forces. They are also tough and resistant to any mechanical damage. They are suitable for professional drilling work in materials classified as P1.2 - P1.3 (alloy steels, metals, metal alloys, plastics and non-ferrous metals). They can be used with conventional drills, lathes and milling machines, as well as CNC numerical control machine tools.
