Simonds 73535500 Slim Taper Saw File 4in

Triangular Profile for Precision Filing

The Simonds 73535500 Slim Taper Saw File is a 4-inch American pattern machinist's tool designed for sharpening saw teeth and finishing acute internal angles. Its rigid triangular profile tapers toward the point, allowing access to tight gullets and corners. The single-cut faces and edges produce a smooth finish on aluminum, brass, bronze, steel and tin. This file suits tradespeople and hobbyists who need controlled material removal in confined spaces.

Single-Cut Geometry Limits Aggressive Stock Removal

The single-cut tooth pattern on all three faces and edges creates a finer surface than double-cut alternatives but removes material more slowly. With 42, 47 or 63 teeth per inch depending on the face, the file is optimised for finishing rather than heavy shaping. The bastard cut coarseness sits between coarse and second cut, offering a compromise that cannot match the speed of a coarse file or the smoothness of a smooth file. Users needing rapid dimension changes should select a different tool.

Four-Inch Length Defines Reach and Capacity

At 4 inches long without the tang, the file handles small to medium saw teeth and narrow slots up to its 1/4-inch width and 15/64-inch thickness. The tapered tip fits openings that wider blunt files cannot enter, while the rigid body resists flexing during push strokes. The natural finish provides tactile feedback on the workpiece. For larger saws, broader surfaces or deeper gullets, a longer or heavier file is required.
