Crescent Nicholson 5-1/2" 2 Cut Half Round Needle File - T37451

The Nicholson half-round needle file with handle has double-cut Swiss pattern teeth on both the flat and round sides for precision filing of straight surfaces, curved surfaces, and corners in fine work. The file tapers slightly toward the point to ease access into small areas. It has double-cut Swiss pattern teeth on flat and round sides for rapid removal of material on delicate or intricate parts. A knurled round handle provides for secure gripping. 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.
