Precision Tooling Experience Since 2004
HEYI's precision tooling experience dates back to 2004. Based in Shenzhen, China, we support manufacturers with PCD, CBN, carbide, micro and drawing-based custom cutting tools for precision machining.
We work with machining teams that need suitable tool geometry, edge condition and application support for small parts, close tolerances, abrasive non-ferrous materials, hardened steels and other demanding workpieces.
Cutting Tool Support Built Around the Application
Our scope covers precision turning, milling, drilling, reaming, boring, grooving, threading and application-specific custom tooling. Tool recommendations depend on the workpiece material, operation, machine setup, tool geometry and required result.
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.

Four Starting Points for a Tooling Review
PCD Tools
For abrasive non-ferrous, composite and hard-brittle workpieces.
View PCD Tools →CBN Tools
For hardened steel, hard cast iron and hard-turning applications.
View CBN Tools →Carbide Tools
For precision turning, boring, drilling, reaming, threading and grooving.
View Carbide Tools →Custom Tools
For drawing-based geometries and application-specific requirements.
View Custom Tools →Talk With HEYI About Your Machining Application
Send the drawing or current tool information, workpiece material, operation, tolerance or surface-finish target, present problem, quantity and required timing. HEYI will review whether an existing product family or drawing-based custom tool is the more suitable starting point.
