0.250″- 0.500″ Diamond Plated Milling Tools
Diamond Electroplated Milling Tools are precision cutting and grinding tools that have a single layer of diamond grit bonded to their surface using an electroplating process (typically nickel plating). This manufacturing method ensures each diamond particle is securely held in place for aggressive cutting and high precision.
Key Features
- Single-layer diamond coating → All abrasive grains are exposed, giving sharp, fast-cutting action.
- Nickel electroplating → Provides strong adhesion of diamond particles to the tool body.
- Custom profiles possible → Shapes can be tailored for specific milling operations.
- Excellent edge definition → Ideal for intricate milling and contour shaping.
Advantages
- Fast material removal due to sharp, exposed diamond particles.
- High precision in profile milling and surface finishing.
- Good heat dissipation because the open structure reduces friction.
- Can be made for complex geometries that sintered diamond tools might not handle well.
Common Applications
Electroplated diamond milling tools are widely used for hard, brittle, and wear-resistant materials such as:
- Glass & fused silica (e.g., precision optics)
- Ceramics (technical ceramics, alumina, zirconia)
- Stone & composites (granite, marble, quartz)
- Carbide & hardened steels (in specific applications)
- Advanced composites (CFRP, GFRP)
- Crystal & semiconductor materials (sapphire, silicon, GaAs)
Tool Types
- Ball-nose milling tools – for 3D contouring and surface finishing.
- End mills – for slotting, pocketing, and edge milling.
- Profile mills – for complex shapes and patterns.
- Router bits – for high-speed CNC milling.
- Custom form tools – tailored for specialty grooves, chamfers, or radii.
