The WILLIAMS COMFORT PRODUCTS 1-170-10-1-2 is a 3-square (triangular) bastard-cut file measuring 10 inches in length with 23 teeth per inch (TPI). This hand file is engineered for deburring, shaping, and dressing internal angles, threads, and grooves on metal workpieces. The triangular profile gives access to 60-degree corners and tight internal angles that flat or round files cannot reach. Tradespeople in HVAC, plumbing, electrical, and mechanical service use files like this for cleaning pipe threads, dressing burrs on conduit cuts, and fitting sheet metal components during installation and repair work.
This file is suited for general trade use across residential and light commercial service applications. It is commonly used when cleaning up rough cuts on metal pipe, tubing, or conduit, and when refining threads or edges prior to assembly. The bastard-cut tooth pattern removes material at a moderate rate, making it appropriate for both initial shaping and intermediate finishing work on steel, copper, aluminum, and similar metals.
Designed as a general-purpose hand file compatible with standard file handles for 10-inch files; suitable for use in HVAC, plumbing, electrical, and mechanical trade applications wherever a triangular bastard-cut file is required.
Hand files should always be fitted with an appropriate handle before use to prevent injury from the tang. Wear appropriate eye and hand protection when filing metal. Keep the file clean and free of metal filings using a file card or brush to maintain cutting efficiency and extend tool life.
