Countersink countersink 12 75 degrees

Professional conical countersink 12 75 degrees made according to the dimensional standard DIN 334. It is a NWSa type countersink designed for machining holes with a maximum diameter of 12 mm, at an angle of 60 degrees. It is suitable both for countersinking, enlarging holes and for face machining of surfaces around holes. The tapered countersinks we offer are extremely durable tools used for machining all commonly used construction materials, including unalloyed steels, metals, nonferrous metals, metal alloys. The countersinks are made of modern HSS (High Speed Steel). It is a steel with enhanced cutting properties. It allows very accurate and high-performance machining. The blades of the tools are very resistant to harsh cutting conditions and also resistant to any mechanical damage. Countersinks are suitable for all types of machine tools, drills, as well as for computer numerical control machine tools in CNC technology.
