Flat Bastard-Cut File, 4 in, American Pattern

Ideal for machinists, machinery builders, ship and engine builders. Can be used effectively by repairmen and others who require rapid removal of metal. Rectangular cross-section allows you to smooth and sharpen straight surfaces, while slight taper in width towards the file's point creates ease of access in slots. Double-cut on the sides for rough filing and single-cut on the edges for a smooth finish.
