These very wide, extra thin files were manufactured to make full contact between the file surface and the workpiece. These unique files are widely used in the plastic molds and in the aluminum extruders industries. The two different file sizes are available in four grits, and thicknesses range between 1/64" (0.4 mm) with grit D30, to 3/64" (1.2 mm) with grit D126. Files are available individually and in three separate kits, as shown below. All files fit into the specially designed handle.
