Router Bit 8 mm Shank Diameter Compression CNC Groove Cutter Spiral Cutter 4 mm Cutting Diameter 20 mm Cutting Length HRC55 Wood Burr for Wood Engraving Milling Machine

Size - The compression spiral router bit has a shank diameter of 8 mm, a cutting diameter of 4 mm, a cutting length of 20 mm and a total length of 75 mm. Spiral cutters allow you to obtain precise and effective cutting results. High quality carbide: The spiral cutters are made of high-quality carbide, ensuring high durability and excellent cutting performance. Compared to ordinary high-speed steel (HSS), carbide provides better durability and heat resistance. Double spiral design: the groove cutter has two sharp cutting edges. The double spiral design of the cutter allows for efficient chip evacuation and reduces vibration during use, resulting in a smoother and more precise cut. Excellent performance: The wood cutter can achieve clean and professional results. The "Compression" Router Bit produces a clean upper and lower surface. Compatible with: Helicoidale cutters are suitable for processing plywood, MDF, particle board, as well as soft and hard wood, and other materials. Router bits can be used in CNC machines, portable routers, milling tables and other machines, integrating seamlessly with existing installations.
