Our SB-shaped carbide rotary burrs are specifically designed for high-efficiency aluminium cutting and shaping applications. Featuring a unique spherical ball nose design, these burrs deliver superior contouring capability while maintaining excellent material removal rates in soft metals.
* Specialized Geometry - SB shape provides 360° cutting ability for complex 3D profiling
* Anti-Galling Design - Proprietary flute pattern prevents aluminium buildup
* Premium Materials - K30 carbide grade with 42CrMo alloy steel shank
* Precision Balanced - <0.005mm runout for vibration-free operation
* Multi-Purpose - Ideal for mold making, aerospace components, and automotive repairs

For Optimal Performance:
Use air-cooled die grinders (recommended 0.5-1.0MPa air pressure)
Maintain 20-30° approach angle for best chip evacuation
Apply aluminium-specific cutting fluid (water-soluble type preferred)
Troubleshooting Guide:
Problem: Excessive burr wear
Solution: Reduce RPM by 20% and check workpiece hardness
Problem: Material sticking
Solution: Increase feed rate or use specialized anti-galling burr
