A diamond system engineered for graphite, 10x longer life

D3*R0.2*4FL*20NL*80 OAL*4SH*4F combines a fine-grain carbide substrate with a graphite-specific diamond coating. On this corner radius tool, lower edge wear helps retain the specified dimensions and cutting profile during production.

D3*R0.2*4FL*20NL*80 OAL*4SH*4F diamond coating and carbide interface

Secure coating-to-substrate interface

The substrate chemistry and microstructure promote dense diamond nucleation, reducing the risk of premature coating separation in abrasive graphite cutting.

D3*R0.2*4FL*20NL*80 OAL*4SH*4F diamond coating versus TiAlN wear comparison

About 74% less edge retreat after 60 minutes

In the shown carbon-resin test, diamond coating records about 0.006 mm edge retreat versus about 0.023 mm for TiAlN. Lower wear supports more consistent machined dimensions.
