Diamond Coated Corn End Mill for Graphite Machining

A diamond-coated corn end mill is a specialized solid carbide cutting tool designed for high-speed, high-precision machining of graphite, carbon composites, and other abrasive non-metallic materials. The corn-shaped (serrated) cutting edge ensures efficient roughing, while the diamond coating provides extreme wear resistance for prolonged tool life.

Key Features

Material: Ultra-fine grain carbide substrate with CVD/PCD diamond coating for superior hardness and reduced graphite adhesion
Geometry: Corn/serrated edge breaks graphite into fine chips, reducing cutting forces
Flute Options: 2-4 flutes balance chip evacuation and cutting speed
Tip Options: Flat or ball-nose tip for flat-bottom or 3D contouring applications
Graphite Optimization: Low helix angle (~10°-20°) to prevent edge chipping with polished flutes to minimize friction
Durability: Diamond coating lasts 5-10x longer than uncoated carbide in graphite applications

Typical Applications

Graphite electrodes for EDM applications in mold & die industry
Carbon Fiber Reinforced Polymers (CFRP), ceramics, and glass composites
High-Speed Machining (HSM) of brittle, abrasive materials
Industries: Aerospace, automotive (EV battery components), electronics, and precision tooling

Performance Advantages

Extended tool life through diamond coating's abrasive wear resistance
Superior surface finish with reduced graphite dust buildup
Higher speeds & feeds compared to uncoated tools
Reduced tool changes saving production downtime

Usage Recommendations

Always use dust extraction - graphite particles are conductive and abrasive
Dry machining or air blast preferred - avoid coolant as graphite absorbs moisture
Climb milling recommended for better chip evacuation and finish
Avoid excessive heat - maintain proper chip removal at high RPMs
