Product Description

The Nicholson 22040N 5-piece American pattern hand file set includes an assortment of file profiles, cuts, and lengths for shaping, sharpening, and removing material. The set includes a 6"/150 mm slim taper, 8"/200 mm mill smooth, 8"/200 mm mill bastard, 10"/250 mm mill bastard, and 10"/250 mm half-round bastard file. The bastard files enable heavy material removal when finish is not a concern, and the smooth files have fine teeth that create a smooth finish. The files have single-cut faces for use with light pressure, except for the half-round file which has double-cut round and flat sides. The files are made from high-carbon steel for high strength and durability. The set comes in a red plastic pouch with each compartment labeled with the file length, shape, and coarseness. Assortment Contents

Files are toothed tools that offer a controlled way to remove material from intricate shapes. The shape of the object being filed establishes which file shape and length should be used. For example, a round file is recommended when filing concave surfaces or enlarging holes. File length measures the cutting face and does not include the handle or tang. The cut and coarseness of the file determines how much material will be removed with each stroke. A single-cut file has parallel rows of teeth covering its face, removing small amounts of material with light pressure to create a fine finish. A double-cut file has similar teeth as a single-cut file but is overlaid with a second set of parallel teeth facing the opposite direction. This second set of teeth increases the amount of material removed with each pass, generates a rougher finish, and requires heavier pressure than a single-cut file. A rasp-cut file has individually formed teeth that are raised above the tool's surface for removing large amounts of material from wood, aluminum, lead, and other soft materials. A curved-cut file has teeth arranged in parallel semicircles across the face of the file and is most commonly used for auto body projects. Most files are classified as American pattern or Swiss pattern, and each has their own coarseness rating system. American pattern files are rated bastard (coarse) cut, second (semi-smooth) cut, and smooth cut. Swiss pattern files are recommended for precision applications and have a larger rating scale from coarse (00) to extra smooth (6). Nicholson manufactures hand tools and power tool accessories.
