Drill 3,1 mm on Morse taper with a fin

Professional metal drill fi 3,1 mm with Morse taper shank for steel, made according to the dimensional standard DIN 345, from modern high-speed steel HSS (High Speed Steel). The drills are produced by the rolling method, according to the latest standards. They have a tip angle of 118 degrees, strong ground edges that are insensitive to impact and lateral forces, and spiral grooves for draining chips up the drilled hole. Morse taper drills are suitable for machining hard and hard-to-machine materials, even in very tough working conditions. The 3 .1 HSS metal drill bits are characterized by greater hardness and durability, as well as resistance to abrasion under the influence of high temperatures generated during high-speed drilling. Suitable for machining hard unalloyed steels, metals, non-ferrous metals, metal alloys and other materials of grade P1.2 - P1.3. Suitable for conventional and CNC numerical control machine tools.
