Countersink countersink 8,3 90 degrees for metal

Countersink countersink8,3 90 degrees with cylindrical shank. Designed for hole enlargement as well as face machining around holes. Professional conical countersink 8,3 90 degrees, NWSa type for machining holes with a maximum diameter of 8,3 mm at an angle of 90 degrees. It is suitable for countersinking, widening, and otherwise shaping the face around holes. The tapered countersinks on offer at our store are made in accordance with the DIN 335 dimensional standard, from a special high-quality HSS high-speed steel. Thanks to its properties, countersinks are suitable for machining all commonly used construction materials from group P1.2 - P1.3 (metals, unalloyed steels, non-ferrous metals, metal alloys, hardened plastics). The countersinks are characterized by high hardness, durability and resistance to harsh working conditions. Their blades are extremely resistant to any mechanical damage, which results in a noticeable extension of the tool life. They are suitable for all types of machine tools, including CNC numerical control machines.
