PR1115 PVD Coating
Kyocera's PR1115 grade is a high-performance PVD coated carbide substrate optimized for precision machining. It provides exceptional wear resistance and heat stability, ensuring the cutting edge remains sharp even when threading tough 300-series stainless steel or heat-resistant alloys. It effectively prevents built-up edge (BUE), a common failure in threading operations.
TF Chipbreaker Function
The TF chipbreaker is specifically designed to manage the unique chip load of threading. By forcing the chip to curl and break quickly, it reduces cutting resistance and prevents long, stringy chips from scratching the thread surface or damaging the tool. This leads to a superior surface finish and predictable tool life.
