Sintered Diamond Bur

The Sintered Diamond Bur is a heavy-duty precision tool engineered for high-speed grinding, shaping, and material removal on ultra-hard substrates like carbides, industrial ceramics, sapphire, and advanced composites. Featuring a sintered metal bond that permanently bonds diamond particles, it delivers unmatched durability and stability under extreme mechanical stress.

Key Features

  • Sintered Diamond Bond: Enhanced diamond retention for aggressive material removal and long-term wear resistance.

  • High-Speed Stability: Optimized for use with rotary tools or CNC machines.

  • Thermal Resistance: Withstands high temperatures during precision machining of heat-sensitive materials.

  • Multi-Profile Designs: Available in cylindrical, ball-end, and tapered shapes for specialized tasks.

Applications

Technical Considerations

  • Material Suitability: Optimized for Mohs 10 materials (e.g., diamond, cubic boron nitride).

  • Operational Limits:

    • Speed: 10,000–30,000 RPM (varies by bur size).

    • Cooling: Mandatory use of coolants to prevent thermal damage.

  • Safety: Wear protective gear (goggles, dust masks) to mitigate debris risks.

Comparison to Resin Bond Tools

Feature Sintered Diamond Bur Resin Diamond Bur
Bond Strength Ultra-durable, metal-bonded Moderate, resin-bonded
Best For Hard materials (Mohs ≥9) Softer materials (Mohs ≤8)
Lifespan 5–10x longer Shorter, prone to wear
Cost Efficiency Higher upfront, lower long-term cost Lower upfront, frequent replacement needed

Ideal for: Aerospace engineers, toolmakers, and high-precision workshops.Explore the Sintered Diamond Bur Series for industrial-grade performance.
