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.
Applications
-
Aerospace & Defense: Machining tungsten carbide components or ceramic armor.
-
Tool & Die Making: Sharpening industrial-grade cutting tools or mold cores.
-
Electronics Manufacturing: Precision shaping of semiconductor substrates or optical fibers.
-
Lapidary & Jewelry: Detailing synthetic gemstones or hardened alloys.
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 |
