Technical Specifications
Carbide Grade
- Tungsten Carbide Grade: K10 / K20 (High wear resistance, ideal for aluminum)
- Hardness: HRA 90+ (Ensures long-lasting sharpness)
- Grain Size: Sub-micron (For finer finishes)
Shank Material
- High-Speed Steel (HSS) Shank - 42CrMo alloy steel, heat-treated for high torsional strength
- Precision Ground - Ensures perfect concentricity (runout
Coating Options (Upon Request)
- TiN (Titanium Nitride) - Increases lifespan by 30%
- TiAlN (Titanium Aluminum Nitride) - Better heat resistance for high-speed applications

Frequently Asked Questions
Why does my rotary burr clog when cutting aluminum?
Cheap burrs have poor flute design. Our burrs feature optimized chip clearance to prevent material buildup.
What's the best speed (RPM) for aluminum cutting?
15,000-30,000 RPM is ideal. Too slow causes clogging; too fast leads to overheating.
Can I use these burrs on stainless steel?
No - these are optimized for soft metals (Aluminum, Copper, Brass). For steel, use Cobalt or TiN-coated burrs.
How long does one burr last?
Under normal use, 5-10x longer than HSS burrs depending on workload.
Manufacturing Excellence
With 15+ years of manufacturing expertise, we provide trusted carbide rotary burrs to metalworking professionals worldwide. Our strict QC process ensures every burr is tested for hardness, concentricity, and cutting performance before shipment.
