Countersink countersink 16,5 90 degrees for metal

Tapered countersink16,5 90 degrees with cylindrical shank. Designed for enlarging holes as well as for face machining of surfaces around holes. Modern conical countersink type NWSa, complying with the dimensional standard DIN 335, is designed for professional processing of holes. First of all, for their countersinking, enlarging and other shaping at an angle of 90 degrees. The maximum diameter of the holes is fi 16,5 mm. The countersinks offered in our store are made of special HSS high-speed steel. This is a unique tool steel, the use of which significantly increases the cutting parameters. First of all, conical countersinks fi 16,5 90 degrees from this steel are resistant to very difficult cutting conditions. They are suitable for high-speed machining at high speeds, during which temperatures as high as 600 degrees are generated. The countersinks retain their resistance to any damage, including fractures, chipping cracks, chipping and others. In addition, countersinks from our offer are suitable for almost all types of machine tools ranging from traditional mechanical machine tools and drills to modern CNC-controlled numerical control machines.
