Diamond coated end mills are made for machining abrasive non-ferrous materials, especially graphite, CFRP, GFRP, and high-silicon aluminum. These materials can wear standard carbide tools quickly. Perciò, a diamond coating helps improve wear resistance, cutting stability, and tool life during CNC milling.
OMIST supplies diamond coated carbide end mills for graphite electrode machining, composite trimming, mold processing, and precision non-ferrous material milling. With 16 years of cutting tool manufacturing experience in China, we support standard sizes, custom dimensions, OEM/ODM service, and drawing-based production.
For broader graphite milling applications, you can also review our fresa diamantata.
What Are Diamond Coated End Mills?
Diamond coated end mills are solid carbide end mills with a diamond coating on the cutting edge. This coating helps protect the cutting edge when machining abrasive materials. Di conseguenza, the tool can keep more stable cutting performance during long cutting cycles.
These tools are often used as graphite end mills, CFRP milling cutters, and high-performance tools for abrasive non-ferrous materials. Compared with uncoated carbide tools, they can help reduce edge wear and support better dimensional stability.
Key Features of Our Diamond Coated End Mills
Diamond Coating for Abrasive Materials
The diamond coating helps improve wear resistance during graphite and composite machining. It also supports more stable cutting performance in abrasive working conditions.
Solid Carbide Substrate
Each cutter uses a solid carbide substrate for rigidity and cutting strength. This structure helps improve tool stability, especially in graphite electrode machining and fine finishing.
Suitable for Graphite and CFRP
These tools are mainly recommended for graphite, CFRP, GFRP, alluminio ad alto contenuto di silicio, e altri materiali abrasivi non ferrosi. Tuttavia, they are not the first choice for steel or stainless steel machining.
Standard and Custom Sizes
OMIST supplies standard specifications and also produces custom tools according to drawings, samples, or detailed requirements. We can adjust the cutting diameter, lunghezza del flauto, lunghezza complessiva, numero di flauto, and end type to match your machining needs.
For non-standard diameters, special flute design, or custom tool geometry, we can also support custom end mills.

Come scegliere le frese con rivestimento diamantato
To choose the right tool, please confirm the workpiece material, cutting diameter, lunghezza del flauto, lunghezza complessiva, end type, and machining purpose. These details help us recommend a more suitable cutter design.
For graphite roughing, tool strength and chip evacuation are important. For graphite finishing, edge quality and surface finish become more important. Inoltre, CFRP and GFRP machining may need a different flute geometry to reduce wear and improve cutting stability.
If you are not sure which graphite milling tool is suitable, you can send us your drawing, sample photo, or machining requirement. Our team will review the details and provide a practical recommendation.

Domande frequenti
What are diamond coated end mills used for?
Diamond coated end mills machine graphite, CFRP, GFRP, alluminio ad alto contenuto di silicio, and abrasive non-ferrous materials. Common applications include graphite electrodes, graphite molds, and composite trimming.
Are diamond coated end mills suitable for graphite?
Sì. Graphite is abrasive, so diamond coating helps improve wear resistance and cutting stability during graphite machining.
Can diamond coated end mills cut steel?
We do not recommend them for steel or stainless steel. For ferrous materials, carbide end mills with suitable coatings usually work better.
Can you customize diamond coated end mills?
Sì. We can customize the cutting diameter, lunghezza del flauto, lunghezza complessiva, numero di flauto, end type, and tool geometry according to drawings or samples.
Do you support OEM and ODM service?
Sì. OMIST supports OEM and ODM service, including custom sizes, tool marking, and packaging requirements.
What information should I send for a quotation?
Please send the workpiece material, cutting diameter, lunghezza del flauto, lunghezza complessiva, end type, quantity, and drawing or sample photo if available.
