The WILLIAMS COMFORT PRODUCTS 1-110-12-2-0 is a 12-inch flat file with a second-cut tooth pattern rated at 28 teeth per inch (TPI). Flat files are hand tools used to remove material, deburr edges, and shape metal or other hard surfaces during fabrication and installation work. The second-cut tooth pattern sits between bastard and smooth cuts, making it suitable for general-purpose material removal where moderate stock removal and a reasonably clean finish are both required. At 0.807 pounds, this file is lightweight enough for extended use in the field or shop. Trade professionals across HVAC, plumbing, and mechanical contracting reach for flat files during rough-in and finishing tasks.
This flat file is well suited for residential and light commercial trade applications. Common tasks include dressing pipe ends, cleaning burrs from copper or steel fittings, removing sharp edges from sheet metal ductwork, and general-purpose metal fitting work on job sites. The 12-inch length provides sufficient working surface for most standard trade filing operations without being unwieldy in tight spaces.
Designed as a general-purpose flat file for use across metal fabrication, HVAC sheet metal work, plumbing rough-in, and similar trade applications where a second-cut flat file is specified.
Flat files are hand tools and require no power source or special code compliance. Always wear appropriate cut-resistant gloves when handling files and workpieces with sharp edges. Secure the workpiece in a vise or clamp before filing to maintain control and prevent injury. Inspect the file tang before use and ensure it is properly fitted with a handle before applying pressure.
