Black OX Half Round Files

• The half round file may be used to file not only on flat surfaces, but concave and convex surfaces too.
• On concave surfaces the file is used with a rolling motion to prevent grooving the work surface
• Great for rounding in holes, corners and crevices
• Double cut on both sides
• Half Round Files feature a built-in twist & roll action on the half round side produced by the spiral cut design with a wavy tooth design on the flat side
