Key Features & Benefits
- 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 by up to 10 times on steel and stainless.
- 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.
- Cylindrical shape with no end cut — ideal for contouring, slotting, and creating flat-bottomed channels without scoring the base of the workpiece.
When to Use This Burr
Choose the SA-2DC (5/16″ head diameter) for deburring, weld preparation, chamfering, and general stock removal where a cylindrical profile is needed. The 5/16″ size is well suited for fine detail work and tight clearances. 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.
