Williams Comfort Products 1-170-04-3-0 3-square File 4 in

Product Description

The WILLIAMS COMFORT PRODUCTS 1-170-04-3-0 is a 3-square file measuring 4 inches in length with a smooth cut profile rated at 71 teeth per inch (TPI). Triangular in cross-section, this file is designed for precision deburring, sharpening, and finishing work in tight angles and confined spaces. The smooth cut tooth pattern removes minimal material per pass, producing a fine surface finish suited to detail work on metal components. Machinists, HVAC technicians, electricians, and plumbers reach for a file like this when cleaning burrs from cut pipe threads, sharpening saw blades, or dressing notched metal edges before assembly.

This 4-inch 3-square file is appropriate for light-duty precision filing tasks across residential and commercial trade applications. Its compact length and triangular profile make it well suited for accessing tight corners, cleaning threaded fittings, refining notches in sheet metal, or sharpening hand saw teeth. It is sold individually and is a standard addition to a trade technician's hand-tool kit wherever fine metal finishing is required.

Installation Notes

This file is a hand tool and requires no power-down or lockout procedure prior to use.
