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.
- Tapered oval profile — combines the reach of a tree shape with the smooth blending of a ball nose for versatile cavity work.
- 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 SE-1DC (1/4″ head) for enlarging holes, blending filleted surfaces, and reaching into rounded cavities. The tapered oval profile combines the reach of a tree shape with the smooth finish of a ball nose. The 1/4″ size is 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.
