12mm Double-Cut Tungsten Carbide Rotary Burr — 6.35mm Shank (1 pc) for Metal & Non‑Metal Grinding

Overview: A double-cut tungsten carbide rotary file engineered for demanding metal and non-metal work, offering exceptional hardness and long life. With a hardness rating up to HRC70, this burr repeatedly outperforms traditional hand files and small grinding wheels, delivering much higher throughput on production tasks. Performance and efficiency: Designed to replace small wheels, this rotary file boosts productivity — its processing speed is several times greater than conventional files and can reach up to 10 times the efficiency of small wheel stalks. It produces precise cavities and a high-quality surface finish suitable for fine machining and finishing operations. Materials it handles: Suitable for a wide variety of substrates including cast iron, cast steel, bearing steel, high carbon steel, chrome-nickel alloy, bronze, brass, ceramic tile, marble, jade, and bone. Use and safety guidance: Compatible with pneumatic and electric tools. Recommended operating speed: 6000–50000 rpm. Always clamp the tool securely during use. Prefer milling and cutting modes and avoid reciprocating cutting to protect the cutter and workpiece. The burr is simple to operate, reliable, reduces worker effort, and helps improve the working environment. Package contents and dimensions: Includes 1 carbide rotary file. Cutter diameter: 12mm. Cutter length: 25mm. Shank diameter: 35mm (1/4 inch). Shank length: 45mm.
