Countersink countersink fi 25 90 degrees for metal

Countersink countersink fi25 90 degrees with cylindrical shank. Designed for enlarging holes as well as for face machining of surfaces around holes. Professional conical countersink designed for enlarging holes as well as for face machining of surfaces around holes. NWSa countersink type. It is suitable for machining holes with a maximum diameter of 25 mm, at an angle of 90 degrees. It is made in accordance with the dimensional standard DIN 335 from special high-grade HSS. This is a unique tool steel, the properties of which affect the quality of machining. Our offered conical countersinks fi 25 90 degrees are very hard and wear-resistant. They are suitable for machining very hard and hard-to-machine materials of P1.2 - P1.3 class (metals, non-ferrous metals, metal alloys, non-alloy steels, plastics). Even in very harsh conditions, they maintain high efficiency and are resistant to any mechanical damage (fractures, cracks, chipping and others). They are suitable for various types of machine tools, including: conventional machine tools, drilling machines, as well as modern computer numerical control (CNC) machines.
