Diamond Coated End Mill for Graphite CVD Coating High Wear Resistance Long Life Graphite Electrode Machining

Graphite-specific diamond-coated mill with proper edge prep. Cutting EDM electrode graphite at 10,000 RPM, 60 IPM dry. Sharp edge, no chipping, coating holds up under abrasive wear. Will be specifying for our EDM department. 5 stars.

Diamond-coated endmill for graphite only — not recommended for steel. We tested on sintered graphite blocks for the EDM department. Tool life was outstanding — 80+ hours. Sharp out of the box. 5 stars for graphite.

Diamond-coated endmill for graphite and abrasive non-metal work. Tested on fine-grain graphite EDM electrodes at 8,000 RPM, 80 IPM dry. Tool life was 60+ hours cumulative — about 4x our previous competitor's diamond-coated mill. Coating is well-bonded; no flaking observed. 5 stars.

CVD diamond-coated for graphite. We replaced Iscar Diamond mills with these and got similar life at a fraction of the cost. Fine-grain graphite at 12,000 RPM, 90 IPM dry. Tool lasted for around 250 cc of material removed. 5 stars.

Diamond CVD-coated for graphite and aluminum. Edge geometry is correct, coating is even, no flaking. Spec'd for our EDM electrode production line. 5 stars for graphite applications.
