Types of items for coating sp³ applies diamond coatings to a wide variety of silicon carbide cutting tools and other carbide items supplied by the customer. See Custom Coating Overview.
Service coating requirements sp³ will apply a diamond coating to most styles of tools furnished by the customer, given they meet sp3 requirements for carbide grade. Inserts should be medium grain size, C2 tungsten carbide – see the list of approved grades below. Inserts will be coated one side only. Sharp and honed edges are acceptable. Lightly honed edges are preferred. sp3 approved grades are the most commonly used grades, but do not preclude other grades from being used as the base carbide. Consult sp3 for additional information regarding acceptable grades of tungsten carbide. sp3 will coat customer supplied round tools if ground from sp3 approved carbide blanks. sp3 will not coat used inserts, TiC-base cermets, CVD or PVD coated inserts, or previously diamond coated inserts. Laser marking affects the adhesion of the diamond and should not be close to a cutting edge.
Specifying the application As with all DIAbide diamond, the selection begins with the Material Application Code. When ordering custom DIAbide parts, always refer to this table and specify which code best fits your application. These are more commonly used grades. If there are questions regarding the application range always contact an sp3 engineer for specific recommendations.
