Half-Round Ring Swiss Pattern Precision Files Swiss pattern files are designed for detail work, delicate finishing, and precise metal removal. They have strict manufacturing tolerances, are uniform in taper, points, sharp edges, dimensions and flatness. These files are made of the finest heat-tempered, chrome alloy steel. They are measured in length from the point where the teeth begin to the end of the file. The handle section (tang) is not included in the file length.
Width and thickness tapered to a point. Narrower than regular half-round and, therefore, useful for filing inside of rings. Double cut on both sides. Length is 6" (150mm). Width is 15/32" (12.0mm). Thickness is 9/64" (3.5mm). Available in 6 cuts; cut 00, 0, 1, 2, 3, and 4.
