Key Features & Benefits
- 14° included angle with radius tip — reaches into tapered cavities, V-grooves, and angled surfaces that cylindrical or ball shapes cannot access.
- CNC precision-ground flutes — delivers consistent cutting performance with reduced vibration and longer tool life across repeated use.
- Double-cut cross-flute pattern — produces finer chips than single-cut, resulting in a smoother surface finish with less chatter on ferrous metals.
- Premium tungsten carbide head — maintains cutting edge hardness at high temperatures, outlasting HSS burrs significantly on steel and stainless applications.
- 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 SL-2DC (5/16″ head) for deburring internal angles, finishing tapered bores, blending weld joints in corners, and cleaning up castings with angled features. The included angle profile lets you work into tight V-channels and tapered openings that flat or ball-shaped burrs cannot reach. The 5/16″ size is suited for fine detail work and tight clearances. Use with a 1/4″ collet die grinder at up to 66,000 RPM.
