Key Features & Benefits
- CNC precision-ground flutes — delivers consistent cutting performance with reduced vibration and longer tool life across repeated use.
- Aluminium Cut flute pattern — single-cut aluminium-specific flute pattern that clears chips rapidly without clogging, designed specifically for aluminium, brass, copper, and soft non-ferrous metals.
- Aluminium-cut flute geometry — wider chip gullets and positive rake angles prevent material build-up and clogging on soft metals.
- Ball nose radius tip — produces smooth concave surfaces and rounded internal corners without sharp edge marks.
- Premium tungsten carbide head — maintains cutting edge hardness at high temperatures, outlasting HSS burrs significantly.
- High-quality alloy steel shank (HRC 45–49) — resists deflection and breakage under load, ensuring safe operation at full RPM in die grinders and rotary tools.
When to Use This Burr
Choose the SC-3AL (3/8″ head) for concave surfaces, fillet radii, rounded channels, and contour blending. The radius tip produces smooth transitions and prevents sharp inside corners. The 3/8″ size is suited for medium-duty shaping and edge preparation. Use with a 1/4″ collet die grinder at speeds up to 66,000 RPM — reduce speed for larger diameters and harder materials for best results.
