The WSKTS-KO Tool Grinding Attachment is designed for home shop tool sharpening and grinding tasks. This two pulley Tool Grinding Attachment is designed with cast metal components to hold up to the rigors of grinding and sharpening tasks like axes and hatchets, mower blades, garden tools and most any tool with a blade. It also makes a handheld belt sander / power file for a wide range of grinding tasks in metal, wood or plastics. It installs quickly thanks to the tool-less design, so changing attachments is quick and easy. The spring tensioner with sealed bearing has a lock out feature that makes belt changes fast and easy without the need for tools – simply push and turn the tensioner to install a belt in seconds. This attachment provides a larger diameter drive pulley to achieve the optimal belt speed (4500 SFM) for a wide range of grinding tasks. On tool belt tracking ensures that you can keep your belt centered while working, without using tools or losing momentum. Attachment allows for both flat platen and slack belt grinding depending on the task at hand without any set up time or parts to adjust. Includes premium Norton extra coarse P60 grit Zirconia Alumina 3/4" x 12” engineered abrasive belts that are designed and intended for heavy stock removal and long life. This attachment also accepts the standard WSKTS-KO belt mix for more light duty grinding or polishing tasks where a finer surface finish or less material take off is desired. Not intended for industrial or commercial applications.
