Diamond coating and edge retention
D2*R1*5FL*60NL*130 OAL*4SH*3F 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.

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 D2*R1*5FL*60NL*130 OAL*4SH*3F.
ZOLLER dimensional inspection

Every tool is checked for critical dimensions and cutting geometry using an optical measurement system. A dimensional report for order code 3TBD 020 003 600 is available for incoming inspection and traceability.
