October 7, 2026 Kyocera PR1535 PVD Coated Inserts for Turning
Engineered by Kyocera Corporation, the Kyocera PR1535 turning inserts provide a reliable, tough grade (S35 / M35 / P35) widely applicable from general steel to difficult-to-cut materials. Featuring a newly optimized cobalt mixing ratio and MEGACOAT NANO coating technology, this insert grade significantly reduces sudden fractures during scale removal and heavy interrupted cutting on stainless steel, titanium alloys, and heat-resistant super alloys (HRSA).
Advanced Carbide Substrate and MEGACOAT NANO Technology in Kyocera PR1535
Machining difficult-to-cut alloys generates extreme thermal and mechanical shock, often leading to rapid edge breakage. The specialized carbide substrate incorporates a coarse grain structure with a uniform particle size, decreasing thermal conductivity by 11% and increasing fracture toughness by 23%. Combined with the MEGACOAT NANO PVD coating—boasting a high hardness of 35 GPa and an oxidation temperature of 1,150°C—the insert effectively prevents thermal cracking, halts crack propagation, and delivers long tool life.
Broad Material Compatibility and Recommended Cutting Speeds
The grade lineup supports stable turning operations across demanding industrial materials and tough machining conditions:
- Stainless Steel Turning: Recommended cutting speed ($V_c$) ranges from 70 to 160 m/min (120 m/min recommended) for excellent fracture resistance.
- Heat Resistant Super Alloys (HRSA): Stable cutting performance within 40 to 60 m/min (50 m/min recommended) to resist severe oxidation wear.
- Titanium Alloys & Mold Steel: Delivers superior shock resistance and crack suppression during interrupted cutting and scale removal at 40 to 60 m/min.
