Premium Carbide Rotary Burrs for Aluminium Cutting
Our carbide rotary burrs for aluminium cutting are engineered for smooth, clog-free machining of soft metals, particularly aluminium alloys, copper, and non-ferrous materials. Made from high-grade tungsten carbide and precision-ground for optimal performance, these burrs ensure minimal vibration, reduced heat buildup, and extended tool life—making them ideal for metal fabrication, automotive, aerospace, and DIY applications.
Why Choose Our Carbide Rotary Burrs?
- Superior Material - K10/K20 carbide grade ensures maximum durability and wear resistance
- Anti-Clog Design - Specially designed flutes prevent material buildup for smoother cuts
- Precision Ground - CNC-machined cutting edges for consistent performance at high RPM
- Wide Compatibility - Works with die grinders, pneumatic tools, and CNC machines
- Multiple Shapes & Sizes - Available in cylindrical, ball, tree, cone, and oval shapes
Technical Specifications & Materials
1. Carbide Grade
- Tungsten Carbide Grade: K10 / K20 (High wear resistance, ideal for aluminium)
- Hardness: HRA 90+ (Ensures long-lasting sharpness)
- Grain Size: Sub-micron (For finer finishes)
2. Shank Material
- High-Speed Steel (HSS) Shank - 42CrMo alloy steel, heat-treated for high torsional strength
- Precision Ground - Ensures perfect concentricity (runout < 0.01mm)
3. Coating Options (Upon Request)
- TiN (Titanium Nitride) - Increases lifespan by 30%
- TiAlN (Titanium Aluminum Nitride) - Better heat resistance for high-speed applications
Production Process - How We Ensure Quality
- Material Selection - Only certified K10/K20 carbide blanks are used
- CNC Grinding - Precision-ground cutting edges for consistent sharpness
- Dynamic Balancing - Reduces vibration for smoother operation
- Rigorous QC Testing - Each burr is inspected for hardness, concentricity, and cutting performance
- Anti-Rust Packaging - Vacuum-sealed to prevent oxidation during shipping

Common Questions (FAQ)
Q1: Why does my rotary burr clog when cutting aluminium?
A: Cheap burrs have poor flute design. Ours feature optimized chip clearance to prevent material buildup.
Q2: What's the best speed (RPM) for aluminium cutting?
A: 15,000-30,000 RPM is ideal. Too slow = clogging; too fast = overheating.
Q3: Can I use these burrs on stainless steel?
A: No—these are optimized for soft metals (Al, Cu, Brass). For steel, use Cobalt or TiN-coated burrs.
Q4: How long does one burr last?
A: Under normal use, 5-10x longer than HSS burrs (depending on workload).
