Key Features & Benefits
- CNC precision-ground flutes — delivers consistent cutting performance with reduced vibration and longer tool life across repeated use.
- Double Cut flute pattern — double-cut cross-flute pattern that produces finer chips than single-cut, resulting in a smoother surface finish with less chatter on ferrous 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-5DC (1/2″ head) for concave surfaces, fillet radii, rounded channels, and contour blending. The radius tip produces smooth transitions and prevents sharp inside corners. The 1/2″ size is suited for heavier stock removal and broader surface work. 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.
