The WILLIAMS COMFORT PRODUCTS 2-303-16-0-0 is a square file with a bastard cut profile, measuring 6.25 inches in length. Square files are single-purpose hand tools used by tradespeople to enlarge square or rectangular openings, deburr metal edges, and clean up slots in metal, plastic, or wood workpieces. The bastard cut designation indicates a medium-coarse tooth pattern, suited for faster material removal where a fine finish is not required. This file is sold individually and is a standard hand tool for HVAC, plumbing, and general mechanical service work.
Square files at this length are commonly used in residential and light commercial maintenance applications. The 6.25-inch body length suits close-quarters filing tasks where a longer file would be unwieldy. Tradespeople reach for this file when fitting conduit knockouts, cleaning up pipe notches, or removing burrs from fabricated metal parts. Its bastard cut makes it effective as a primary shaping tool before switching to a finer cut for finishing passes.
Designed as a general-purpose hand file compatible with standard file handles sized for files in the 6-inch class; no proprietary fitment restrictions apply.
This tool requires no installation. Use appropriate personal protective equipment including safety glasses and cut-resistant gloves when filing metal. Secure workpieces in a vise before filing to maintain control and prevent injury. Inspect the file for cracks or damaged teeth before each use and retire any file showing structural defects.
