Tapered countersink fi 40 mm 90 degrees DIN 335 C HSS is a high-end tool for countersinking tapered screw heads and face machining in a wide range of materials. Made in accordance with DIN 335 C from HSS high-speed steel, it provides durability and precision machining in professional applications.
The use of three working blades enables even cutting without vibration, resulting in better surface finish and longer tool life. The fi 40 mm 90-degree conical countersink works well in high-speed machining, even at elevated temperatures, up to six hundred degrees Celsius.
Ideal as a conical countersink for metal, it can be successfully used for structural steels, aluminum, brass, and also as a fi 40 mm 90 degree conical countersink for stainless steel, using cooling. The high-quality cutting surface reduces cutting resistance and facilitates chip evacuation, resulting in higher working efficiency.
- Three working blades - ensure quiet and stable operation of the tool, reducing the risk of vibration.
- HSS steel - wear-resistant, allows machining at high speeds and temperatures.
- High-quality cutting surface - provides clean and precise edges without burrs.
- Universal use - as a conical countersink for metal and for demanding materials such as inox.
- Large working diameter - allows countersinking holes up to a diameter of forty millimeters.
Conical countersink fi 40 mm 90 degrees is a proven solution for factories looking for precision, reliability and durability in daily machining.
