Carbide tap for machine tool
WALTER

The new Prototex HSC is the first solid carbide tap for long-chipping materials. The innovative tap is designed for through holes and is based on a special solid carbide that exhibits a high degree of wear resistance and simultaneous toughness. The application area is intended for steel and long-chipping materials up to approx. 1200 N/mm² tensile strength.

Prototex HSC
- Special solid carbide with increased wear resistance and high toughness
- Optimised spiral point guarantees greater process reliability when used with long-chipping materials
- Increased number of flutes and TiCN-hard material coating for maximum wear resistance and a very long service life
- Lubrication grooves on the shaft ensure optimum cooling
- Up to 3 times the cutting speed in comparison to conventional HSS-E taps
