Crescent Nicholson 1 4inch x 8inch Round Knurl Cut Chainsaw File - 02147N

The Nicholson round chain saw hand file is 8" long and 1/4" in diameter, and has knurl-cut American pattern teeth for filing chain saw cutters. The knurl-cut American pattern teeth help sharpen to a keen edge. 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. Nicholson manufactures hand tools and power tool accessories. The company is headquartered in Sparks, MD.
