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.Sintered Diamond Drill Bit is a high-performance tool engineered for precision drilling in hard materials such as stone, glass, ceramics, and gemstones. Its unique double bevel design enhances both centering and cutting efficiency, making it ideal for clean and accurate hole-making in lapidary and industrial applications.6mm Shaft Diamond Grit:46Grit
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
-

-
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 |
