Durable ABS construction for longterm use: robust, impact resistant and resistant to deformation, delivering lasting durability and wear resistance over time. Easy to use: simplified sliding action and seamless clamping enable smooth operation without requiring advanced skills or extra effort. Enhanced control for precise results: improved alignment minimizes offset errors and enables accurate bit sharpening, yielding uniform polishing and precise grinding while improving handling and sharpening efficiency. Broad compatibility for various bit sizes: designed to accommodate different bit diameters and types, supporting a wide range of tooling needs. Versatile applications: suitable for woodworking, metalworking, construction, automotive , and other industrial tasks that involve bit sharpening and edge finishing. Use scenarios: 1) Woodworking : sharpen router bits and chisels to maintain clean edges and efficient cutting. 2) Metalworking workshop: deburr and sharpen drill bits for smoother performance and longer tool life. 3) Construction or automotive site: onsite bit maintenance to reduce downtime and extend tool longevity.
