Features
- Durable Tungsten Carbide Construction: Crafted from high‑grade tungsten carbide, the bur resists heat, wear and deformation under high‑speed rotation — delivering extended tool life and consistent performance.
- Sharp Cutting Edges: Precision‑machined flutes allow the bur to quickly and cleanly cut, grind and polish a wide variety of materials — including metals, plastics, wood and ceramics.
- 90° Bearing Design for Balanced Rotation: The 90° bearing ensures smooth, even rotation with minimal vibration for tighter control and a more precise finish.
- Versatile Application Across Materials: Tailored for both professional and DIY use, this bur is effective for tasks including metal shaping, plastic and woodwork, ceramic finishing, rust or corrosion removal, and surface polishing.
- High-Speed Efficiency: Optimized for rotary tools at high RPM, this tool enables efficient material removal without sacrificing precision or finish quality.
- Reduced Vibration & Improved Finish: The high concentricity and quality manufacturing of tungsten‑carbide burs help reduce chatter and vibration, enhancing control and reducing operator fatigue.
- Extended Tool Life for Better Value: Tungsten‑carbide burs maintain sharpness far longer than standard high‑speed steel tools, making them more cost-effective for frequent use.
- Access for Detail Work (Size 6 / 1.9 mm): The 1.9 mm diameter head offers a great balance of reach and stability, enabling detailed work in tight spaces while providing enough durability for more robust applications.
- Compatible with Standard Shank Systems: Designed to fit most standard 3/32″ shank rotary tools and handpieces, ensuring ease of use without needing special adapters.
