The Nicholson hobby file set is an assortment of 6 files in a variety of shapes that are 5-1/2" long and have double-cut Swiss pattern teeth for a range of home or shop uses. The Swiss pattern teeth are double-cut for rapid material removal, with high precision for work on delicate or intricate parts. The built-in handle of each file is round and knurled for a secure grip. The set comes in a vinyl pouch for storage.
Hand files are used to remove material and smooth and shape workpieces. They have forward-facing cutting teeth and cut when pushed over either a stationary or rotating workpiece. Single-cut teeth are single rows cut diagonally across the width of the file. Double-cut teeth have two sets of rows cut in opposite directions. American pattern files have three coarseness grades. Coarse, also known as bastard cut, is suitable for efficient, heavy material removal where finish is not a concern. Medium, also known as second cut, offers average material removal and finish quality. Fine, also known as smooth cut, provides the smoothest finish. Swiss pattern files have eight coarseness grades, from 00 (coarse), 0 (medium), and 1 to 6 (fine to finest), offering a smoother finish than equivalent American pattern files. For Swiss pattern files the length of the tool is the length of the blade, not counting the tang, which is the pointed end fitted for a handle; for American pattern files the length of the tool is its entire length, including the tang.
