The WILLIAMS COMFORT PRODUCTS 4-186-08-2-0 is a slim taper file measuring 8 inches in length with a 43 teeth-per-inch (TPI) cut pattern. Slim taper files are hand tools used for precision filing, deburring, and sharpening in tight or narrow spaces where a standard flat file cannot reach. The tapered profile narrows toward the tip, allowing work in confined grooves, slots, and chain saw teeth. Technicians across plumbing, HVAC, electrical, and general mechanical trades keep files like this in their service kits for field deburring of pipe ends, sharpening of cutting edges, and dressing of metal surfaces.
This slim taper file is suited for both shop and field use wherever fine material removal is required. The 43 TPI rating places this file in the fine-cut category, making it appropriate for finish work, sharpening applications, and situations where minimal material removal per stroke is needed. It is sold individually and is a practical addition to any trade service toolkit.
Designed as a general-purpose slim taper file compatible with standard hand-filing applications across trade and mechanical service work. No specific tool system or brand compatibility is stated by the manufacturer for this item.
Hand files require no power source and no special setup, but safe use practices apply. Always use a properly fitted handle when working with files that have a tang, and wear safety glasses to guard against metal filings. File in one direction only — on the forward stroke — to preserve the cut teeth and avoid injury. Inspect the file for cracks or damage before each use and discard any file that shows signs of breakage.
