Simonds 4 in Mill File

The Simonds 73141500 is a 4-inch rectangular mill file with a smooth single-cut pattern on all four edges. It is designed for machinists and metalworkers who need precise material removal on aluminum, brass, bronze, steel, and tin. The rigid construction and taper toward the point allow controlled finishing work in tight spaces.

Thermals Noise Power

As a non-powered hand tool, this file produces no operational heat, audible noise, or electrical power draw during use. Performance depends entirely on the applied manual force and stroke technique. The natural finish on the file body resists corrosion without requiring external cooling or energy input.

Boxed Storage Benefit

The file ships in a protective box that prevents tooth damage during transport and keeps the cutting edges sharp until first use. This packaging supports organised storage in a tool chest or drawer, reducing the risk of accidental contact with other tools. No additional software or accessories are included with this item.

Questions about this item

How do I secure the 4 in file in a handle, and which step is often missed?

Insert the tang fully into a handle sized for the 5/64 in thickness; the step often missed is seating the tang completely so the 7/16 in wide file cannot rotate under pressure.

What replacement will this 44 teeth-per-inch smooth single-cut file need as the edges wear?

The file itself is the wear item; once the single-cut teeth on all four edges dull on aluminum, brass, bronze, steel or tin, replace it with another 4 in smooth mill file.

At what point does the 5/64 in thick rectangular profile limit sustained filing?

The rigid 5/64 in thick body resists flex, but the 4 in length and 44 TPI smooth cut limit material-removal rate before the teeth load up on soft metals.
