Diamond coating and edge retention
A diamond system engineered for graphite, 10x longer life
D4*R2*14FL*70NL*120 OAL*6SH*2F combines a fine-grain carbide substrate with a graphite-specific diamond coating. On this ball nose tool, lower edge wear helps retain the specified dimensions and cutting profile during production.
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.
AK06 fine-grain carbide substrate
AK06 uses high-quality fine WC powder with controlled grain size and morphology, providing a diamond-compatible substrate for D4*R2*14FL*70NL*120 OAL*6SH*2F.
ZOLLER dimensional inspection
