Abstract

A file holder configured to attach a prior art surform file to a prior art linear sander. The file holder includes conventional mounting means allowing it to be attached to the linear sander. A clip recess is provided on the file holder's first end. This feature is shaped to engage and hold the canted clip found on the first end of the surform file. A movable tensioning block is located on the second end of the file holder. It engages and holds the canted clip found on the second end of the surform file. Tensioning means are provided so that the user can adjust the tensioning block to place the surform file in tension. A chip cavity is located in the file holder adjacent the non-cutting side of the surform file. Ejection ports are provided in the side of the file holder. These allow chips collected in the chip cavity to escape the file holder.
