Introduction
CBN and diamond are both superabrasives, but they are not interchangeable in every application. Choosing the wrong abrasive can reduce wheel life, generate heat, damage the workpiece or create inconsistent grinding results.
CBN Grinding Wheels
CBN grinding wheels are commonly used for hardened steel, high speed steel, tool steel, chainsaw chains and precision metal parts. They are valued for profile stability, long service life and reduced dressing frequency.
Diamond Grinding Wheels
Diamond grinding wheels are preferred for tungsten carbide, glass, ceramics, stone, quartz and many non-ferrous materials. They provide strong cutting performance on hard brittle materials and can be supplied in resin, vitrified, metal or electroplated bonds.
Application-Based Selection
Use CBN for hardened steel and HSS tool grinding. Use diamond for carbide tool grinding, glass edge grinding, ceramic grinding, stone grinding and quartz processing. If your application involves mixed materials, send the workpiece details before ordering.

Is CBN better than diamond for steel?
For hardened steel and high speed steel, CBN is usually preferred because it performs well on ferrous materials.
Is diamond better for carbide?
Yes. Diamond grinding wheels are normally recommended for tungsten carbide, glass, ceramics, stone and quartz.
Can one wheel grind both steel and carbide?
A wheel can sometimes handle mixed work, but the best specification depends on the main material, finish target and grinding process.
