1. PCD Grade and Application
| Grade | Granularity(μm) | Characteristics | Application | Microstructure |
| CDW850 | Submicron | Ultra-fine grain structure, strong edge sharpness and edge durability | High precision machining, mirror surface machining, suite for aluminum alloy that required high on the chipping performance, mainly used for machining Ti alloy and other composites | .png) |
| CDW002 | 2μm | High cobalt content, Good electrical machine performance, excellent toughness, Good roughness machining, more convinent for complec tool processing | Mainly used for engrave milling cutter and thread cutting tool, and also cutting tools for wear-resistant parts, used in woodworking saws, particleboard and the tools for machining silicon aluminum alloy | .png) |
| CDW005 | 5μm | Excellent electric spark and machinability, good toughness, wear resistance and edge quality | It suits for good surface quality processing, mainly used for machining PMMA, Silicion alloy and metal cell phone shell outlin and used in the wood cutting tools, saws industry | .png) |
| CDW010 | 10μm | Universal PCD Grade, good toughness and high abrasive resisitance | Suit for single tool for rough machining, especially for wood molding, medium and low silicon aluminum alloy parts (such as piston) | .png) |
| CDW025 | 25μm | High wear resistance and edge quality | Suit for high Silicion Aluminum alloy, MMC, Tungsten carbide and ceramic, graphite,wear resistant parts, mainly used in wood Wood finishing insert and saws | .png) |
| CDW302 | 2~30μm | Mixed 2μm and 25μm,good wear resistance and edge quality and edges strength | It mainly used for machining MMC, high Silicion Aluminum calloy, high strength cast iron and other application. | .png) |
