October 21, 2026 Kyocera PR015S Insert Grade for Hardened Material
The Kyocera PR015S Insert Grade is designed by Kyocera to provide long tool life and stable machining in hardened steel applications. Featuring optimized substrate technology and advanced PVD coating, this grade effectively minimizes heat concentration and notch wear during heavy-duty milling operations.
Key Features of Kyocera PR015S Insert Grade
Engineered for high-hardness milling, this insert grade incorporates key material advances that enhance thermal conductivity and edge toughness.
- Optimized Carbide Substrate: Combines micro-grain and coarse-grain tungsten carbide (WC) with heat-resistant binder phases to improve thermal conductivity and prevent sudden fracturing.
- MEGACOAT HARD Coating: High-hardness and oxidation-resistant PVD film with high aluminum content that resists boundary damage and adhesion at elevated temperatures.
- Reduced Notch Wear: Excellent thermal properties dissipate cutting heat from the edge, promoting consistent tool life on materials above 50 HRC.
- Versatile Cutter Compatibility: Works seamlessly across multiple Kyocera milling cutter platforms including 90°, 45°, 66°, and 88° entry angles.
Compatible Cutter Platforms
The PR015S grade is available across a wide selection of high-efficiency indexable milling bodies:
- MEW Series: High-efficiency 90° milling cutter.
- MFPN45 Series: High-efficiency 45° face milling cutter (PNMU12 type).
- MFWN Series: Low cutting force 90° shoulder cutter (LOMU10/15 type).
- MFPN66 Series: High-efficiency 66° face cutter (PNMU09 type).
- MFSN88 Series: High-efficiency 88° face cutter (SNMU13 type).
