Crescent Nicholson 10" Half Round Double Cut Bastard File - 04995N

The Nicholson coarse grade half-round hand file is 10" long and has one flat side with double-cut American pattern teeth and one curved side with single-cut American pattern teeth for use on flat and curved surfaces. It has double-cut coarse (also called bastard) grade American pattern teeth on the flat side for rapid material removal and single-cut coarse grade teeth on the round side for sharpening and deburring with a rough finish. The tang can be used with an optional handle for secure gripping (sold separately).

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 have 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, more precise finish than equivalent American pattern files.
