Kyocera PR1625 PVD Coated Carbide Inserts
Kyocera PR1625 PVD coated carbide inserts are engineered to deliver extended tool life and high operational stability for shallow grooving applications across continuous and interrupted cutting environments. Manufactured by Kyocera, this tough cemented carbide grade features advanced MEGACOAT NANO coating technology, making it ideal for precision groove widths ranging from 0.33mm to 4.8mm in automotive and general steel components.
Advanced MEGACOAT NANO Coating Technology
The superior performance of Kyocera PR1625 is driven by a specialized multi-layer coating structure applied over a tough micro-grain carbide substrate:
- Nano Laminated Coating Layer: Increases coating hardness by 15% compared to conventional PVD coatings, significantly boosting wear resistance.
- Reduced Wear Coefficient: Lower friction coefficient (reduced by 20%) improves adhesion resistance, preventing chip welding during continuous turning.
- Tough Micro-Grain Substrate: Provides exceptional fracture toughness, offering up to 1.5 times greater fracture resistance during interrupted grooving.
- GM Chipbreaker Geometry: Large lineup engineered for smooth chip control, preventing chip jamming in shallow slots.
Machining Application and Performance
Compared to general-purpose grades like PR1215, Kyocera PR1625 excels in both continuous and heavy interrupted cuts, such as grooving operations on automotive engine drums and transmission shafts. Internal testing demonstrates up to 1.6 times longer tool life over conventional PVD grades while maintaining stable groove dimensions.
