Square machinists file 73428000

The Simonds 73428000 is a 6‑inch American‑pattern square file with a bastard‑cut, double‑cut face and safe edges. It is intended for machinists and metalworkers who need a rigid hand tool for shaping aluminium, brass, bronze, steel and tin.

Bastard‑cut double‑cut limits

The bastard‑cut pattern delivers 33 to 36 teeth per inch, giving a coarseness suited to rapid stock removal rather than fine finishing. The double‑cut face cuts on both diagonals, while the safe edges prevent scoring adjacent surfaces during narrow‑slot work.

Check tang and handle fit

The file body measures 6 in without the tang and is 1/4 in thick and wide, tapering toward the point. Verify that your existing handle or collet accepts a 1/4 in square shank and that the overall length matches your bench space before ordering.

Questions about this item

Which Simonds file matches the 73428000 model and what material range does it cover?

The 73428000 is a 6-inch square machinist file with bastard double-cut teeth designed for aluminum, brass, bronze, steel and tin.

How do the 33 to 36 teeth per inch perform on steel in a workshop?

The bastard double-cut pattern with 33 to 36 teeth per inch removes material quickly on steel while leaving a finish that can be smoothed with a finer file.

Does the safe-edge design change how the file fits in a standard tool box?

The safe edge adds no extra width; the file remains 1/4 inch thick and 6 inches long, so it fits the same slots as a standard square file.
