Tapered countersink 20.5 90 degrees for metal
Conical countersink20,5 90 degrees with Morse taper shank. Designed for hole enlargement as well as face machining around holes. Professional NWSb countersink, conforming to DIN 335-B dimensional standard. Designed for countersinking, enlarging and other machining of holes at 90 degrees. Their maximum diameter is 20,5 mm. The offered 20.5 90-degree tapered count ersinks are suitable for machining hard and hard-to-machine materials, including carbon steel (unalloyed), copper, bronze, aluminum, brass and plastics. Their high resistance to tough cutting conditions is due to the use of modern HSS high-speed steel for their production. Thanks to its properties, countersinks are very hard, durable and resistant to abrasion under high temperatures (up to 600 degrees C). They can be used for high-performance and precision machining. The ability to machine at high speeds makes it possible to reduce overall machining time, and it is also possible to reduce overall machining costs. Tapered countersinks from our store can be used for various types of machine tools, including CNC machines.
