Diamond coating and edge retention
D3*R0.2*4FL*20NL*80 OAL*4SH*2F 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.

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

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 uses high-quality fine WC powder with controlled grain size and morphology, providing a diamond-compatible substrate for D3*R0.2*4FL*20NL*80 OAL*4SH*2F.
ZOLLER dimensional inspection

Every tool is checked for critical dimensions and cutting geometry using an optical measurement system. A dimensional report for order code 2DCR 030 002 200 is available for incoming inspection and traceability.
