Tungsten Carbide Rotary Burr — 3 mm (1/8") Shank, 6 mm (1/4") Cutting Diameter Key benefits Precise, efficient material removal: double-cut (cross-cut) design produces small, uniform chips for faster cutting and a smoother finish compared with single-cut burrs. Long-lasting performance: made from tungsten carbide for high hardness, wear resistance and corrosion resistance, maintaining cutting performance under frequent use. Broad compatibility: 3 mm (1/8") shank fits most rotary tools, handheld electric grinders and many lathe setups for flexible workshop use. What this tool does for you Speeds up deburring, shaping and chamfering by cutting consistently and leaving a cleaner surface. Reduces time spent on secondary finishing thanks to uniform chip formation and efficient material removal. Stands up to tough materials and repeated jobs because of its durable carbide construction. Specifications Shank diameter: 3 mm (1/8") Cutting edge diameter: 6 mm (1/4") Cutting type: double-cut (cross-rilled) design Material: tungsten carbide Compatible materials and applications Metals: stainless steel, iron, bearing steel, alloy steel, copper, aluminum Non-metals: jade, wood, glass, ceramic Typical uses: metalworking, jewelry making, woodworking, welding seam cleanup, chamfering, casting cleanup, carving Practical use scenarios Jewelry making: accurately shape and finish small metal or jade components with controlled chip removal for fine detail work. Metal fabrication: deburr and chamfer welded stainless steel edges and clean castings to reduce finishing time before painting or assembly. Wood and mixed-material projects: carve details in wood or trim composite parts while keeping heat and tear to a minimum due to efficient cutting. Notes for best results Fit the 3 mm (1/8") shank securely in a matching collet or chuck. Use appropriate speed and light, steady pressure for cleaner cuts and longer tool life. Compatible with most rotary and handheld electric tools as well as many lathe setups; always follow your tool manufacturer’s safety and speed recommendations.
