Custom PCD, CBN and Micro Cutting Tools for Precision Machining
HEYI supplies PCD, CBN, carbide and micro cutting tools for precision turning, milling, drilling, reaming and difficult-material machining. Send your drawing, workpiece material and target result for a technical review.
Precision Tooling Experience Since 2004
HEYI's precision tooling experience dates back to 2004. Based in Shenzhen, China, we support precision machining projects with PCD, CBN, carbide and micro cutting tools, including drawing-based custom tooling for specific applications.
Start with the workpiece and machining task
PCD Tools
For aluminum alloys, copper, graphite, CFRP/GFRP, ceramics and other abrasive non-ferrous or hard-brittle materials.
View PCD Tools →CBN Tools
For hardened steel, hard cast iron, rolls, brake components and hard-turning applications where wear stability matters.
View CBN Tools →Carbide Tools
For precision turning, boring, drilling, reaming, threading and grooving across a broad range of machining tasks.
View Carbide Tools →Custom Tools
For drawing-based geometries, reach limits, special forms, insert-pocket fit and application-specific tooling.

PCD Tool Manufacturing and Quality Control
PCD tool slotting and flute generation, cutting-edge generation and sharpening, precision grinding, inspection, and suitable tool repair or reconditioning are completed in the factory. The exact route depends on the tool geometry, workpiece material, machining operation and required result.
What to send for a tooling review
Send the tool drawing or model, workpiece material and hardness, operation and machine type, tolerance and surface-finish target, current setup or failure mode, quantity and required timing.
