The Nicholson flat hand file for aluminum has a rectangular shape with double-cut American pattern Type A teeth on both sides for smoothing and shaping straight surfaces, and provides good chip clearance for a smooth finish when filing aluminum.
Reproducing complicated patterns is a breeze with this 10” Contour Gage. The 3” deep fingers mold into the shape of any surface, creating a template which can then be used for reproducing complex contours and patterns when fabricating sheet metal.
