October 7, 2026 Kyocera PR115S PR120S PVD Coated Inserts for HRSA
Engineered by Kyocera Corporation, the Kyocera PR115S PR120S PVD coated carbide inserts deliver exceptional endurance and maximum tool life when turning heat-resistant super alloys (HRSA) and stainless steel. Featuring a unique heat-resistant carbide substrate combined with newly developed MEGACOAT TOUGH PVD coating technology, these inserts effectively solve various machining issues such as crater wear, notch wear, and rapid edge deterioration under extreme cutting heat above 1,000°C.
Advanced Substrate and MEGACOAT TOUGH Technology in Kyocera PR115S PR120S
Machining heat-resistant super alloys causes rapid work hardening and severe thermal stress on cutting edges. The specialized PVD coating technology, MEGACOAT TOUGH, works in synergy with a unique heat-resistant substrate to control abrasive wear and diminish notching damage. This formulation preserves dimensional accuracy, reduces surface roughness, and maintains high cutting stability even under severe thermal and mechanical stresses.
Specialized Chipbreakers and Precision Machining Support
To further enhance performance, the insert series features dedicated chipbreakers tailored for heat-resistant super alloys:
- SQ / SG / SX Chipbreakers: Optimized geometries designed for low cutting force, superior chip control, and suppression of burr formation.
- Positive Inserts Lineup: Compact configurations engineered specifically for small parts turning and precision component fabrication.
