Countersink countersink fi 20,5 90 degrees for metal

Countersink countersinkfi 20,5 90 degrees with cylindrical shank. Designed for enlarging holes as well as for face machining of surfaces around holes. Conical countersink 20,5 90 degrees made in accordance with DIN 335, type NWSa. Designed for professional machining of holes with a maximum diameter of 20.5 mm, at an angle of 90 degrees. It is suitable both for countersinking, enlarging and other shaping of holes. Tapered countersinks offered in our store are professional cutting tools that can withstand very heavy cutting conditions. First of all, they are resistant to abrasion under the influence of high temperatures generated during high-speed machining. This makes it possible to achieve high cutting performance, while maintaining high precision machining. The countersinks in question are resistant to any mechanical damage (breakage, cracking, chipping, chipping), which makes it possible to significantly extend their service life and reduce overall machining costs at the same time. The countersinks are suitable for various types of machine tools, including professional CNC Machines.
