Carbide Cutter Set — Tungsten Carbide, 3.2 mm Shank Why this set helps you work faster and cleaner Fast material removal: The double-cutting-head design removes material quickly and reduces the need for time-consuming hand filing or sanding. Durable, heat- and corrosion-resistant: Made from tungsten carbide steel for high hardness, long life, and reliable performance under heat and stress. Consistent finish: Designed to improve cutting efficiency and produce a smoother polish and cleaner edges compared with manual filing. Key specifications and compatibility Material: Tungsten carbide steel (high hardness, corrosion and heat resistant). Shank diameter: 3.2 mm — fits most standard rotary tool collets for this size. Recommended tools: Electric multifunctional rotary tools, handheld electric or pneumatic rotary tools. Not recommended for battery-powered multifunctional tools. Maximum compatible speed: up to 50,000 rpm. Functions and applications Multi-use: Suitable for engraving, drilling, polishing, and deburring. Work materials: Effective on wood, aluminum, general metals, and plastics. Practical use scenarios Metal fabrication: Quickly deburr weld seams and clean up rough edges on aluminum brackets before final assembly. Woodworking detail work: Carve or shape small wooden parts and create smooth contours without switching to coarse files. Plastic and model making: Trim flash and refine holes or molded parts with precise control and a clean finish. Tips for best results Use within the recommended speed; ensure the tool collet securely holds the 3.2 mm shank. Wear appropriate eye and respiratory protection when cutting metal, plastic, or wood. For prolonged tool life, avoid excessive side pressure and allow the cutter to do the cutting. This carbide cutter set offers reliable material removal, broad material compatibility, and durability for everyday engraving, deburring, and polishing tasks.
