Drill 7,2 mm on Morse taper with fin

Drill fi 7,2 mm with Morse taper shank for steel NWKc, made of HSS, designed for industrial drilling of holes in very hard and hard-to-machine materials classified as P1.2 - P1.3. It is a drill bit for unalloyed steel, metals, non-ferrous metals, metal alloys and plastics. It has a Morse taper chuck, spiral grooves for removing chips from the drilled hole, strong cutting edges as well as two central blades with an angle of 118 degrees. The 7.2 metal drill bits are characterized by increased resistance to high temperatures (up to 600 degrees C) generated during high-speed drilling. In addition, its advantage is a much higher resistance of the blades to possible fractures, cracks, chipping and other mechanical damage. It is suitable for conventional drilling machines, lathes and milling machines as well as CNC automatic machines. The drill is dedicated to amateur drilling and multi-batch (industrial) machining.
