Diamond-coated solid carbide · factory direct
Fourteen graphite-specific end mill families built on a carbide grade selected for strong diamond-coating adhesion. Dense, secure coating and individually inspected cutting geometry help retain edge accuracy in abrasive graphite production.
Coating and edge-retention evidence
The carbide rod grade is selected for compatibility with diamond deposition. Its surface chemistry and microstructure promote dense diamond nucleation and a firmly bonded coating interface, reducing the risk of premature coating separation.
In the supplied carbon-resin machining comparison, edge retreat at 60 minutes is about 0.006 mm with diamond coating versus 0.023 mm with TiAlN. Lower wear helps the cutting edge hold its geometry and machining accuracy for longer.
Grade AK06 is made from high-quality fine WC powder using a special process that controls grain size and morphology. Its strong compatibility with diamond coating makes it suitable for cutting tools used to machine graphite and composites.
ZOLLER measurement system
ZOLLER optical measurement verifies cutter diameter, corner radius, cutting geometry, and runout. Every end mill is inspected, and a dimensional report can be supplied for acceptance and traceability. This inspection standard is our practical precision advantage over Korean peers such as JJTOOLS.

We use a carbide rod grade selected for compatibility with diamond deposition, helping create a dense coating and a strong coating-to-substrate interface.
Use 2 flutes for maximum chip room and roughing; 3 flutes for a balance of clearance and rigidity; 4–6 flutes for stable high-speed finishing in a rigid setup.
Diamond-coated carbide is suitable for many abrasive composites, but composite geometry can differ from graphite geometry. Share the laminate, thickness, operation, and delamination limits for selection.
Yes. Every end mill is dimensionally inspected, and a report can be supplied for order acceptance and traceability.
Abrasive-material machining
A diamond or diamond-like coating protects the sharp carbide edge against abrasive wear. The solid carbide substrate delivers rigidity and finish quality beyond high-speed steel or cobalt tooling, while the coating supports longer production runs and fewer tool changes.
Carbide and diamond coatings are extremely hard but brittle. Control tool runout, workholding, overhang, and entry strategy to reduce chipping or breakage.
Fewer flutes leave more chip space for plunging, slotting and roughing. More flutes improve stability and finish at high spindle speed when chip evacuation is controlled.
In suitable graphite applications, diamond-coated carbide can run faster and last up to 30× longer than conventional carbide. Actual results depend on graphite grade, machine rigidity, toolpath, and cutting parameters.
Attach a drawing or existing tool code, diameter list, coating requirement, work material/graphite grade, and annual quantity. We will confirm the closest standard series or propose an OEM geometry.
