Conical countersink 20 120 degrees for metal
NWSa conical countersink for professional countersinking, enlarging and other face machining around holes at an angle of 120 degrees. The maximum diameter of the holes is 20.5 mm. The countersinks in our store are manufactured with the highest precision from special HSS high-speed steel. Thanks to its properties, 20,5 120-degree tapered countersinks are much more resistant to very harsh cutting conditions. First of all, they are very hard, durable and resistant to abrasion under the influence of high temperatures generated during high-speed machining.
The blades are resistant even to temperatures as high as 600 degrees C. The countersinks we offer are resistant to potential mechanical damage, such as fractures, cracks, chipping, chipping and others. This extends the use of countersinks and the possibility of reducing overall machining costs. They are suitable for machining carbon steels, metals, nonferrous metals, metal alloys and other hard and hard-to-machine materials of P1.2 grade - P1.3.
