Williams Comfort Products 1-143-04-3-0 Mill File 4 in

Product Description

The WILLIAMS COMFORT PRODUCTS 1-143-04-3-0 is a 4-inch smooth cut mill file rated at 75 teeth per inch (TPI). Mill files in this cut range are used for fine finishing, deburring, and dressing metal surfaces where a clean, smooth result is required. At 0.062 pounds, this file is lightweight and easy to handle during close-tolerance hand filing work. Tradespeople working with metal components, including HVAC techs dressing valve seats or electricians cleaning conduit ends, reach for smooth-cut mill files when surface finish matters.

This 4-inch mill file is suited for light finishing work on metal parts in residential and light commercial trade applications. Its compact length makes it practical for confined spaces and detail work on small metal components. The smooth cut at 75 TPI removes minimal material per stroke, making it appropriate for final passes rather than aggressive stock removal. It is sold individually and is a standard hand tool kept on most service vans and shop benches.

Installation Notes

Mill files are hand tools and require no power source or special installation. Always secure the workpiece before filing to prevent movement and injury. Use a proper file handle to protect the hand from the tang. Inspect the file for cracks or damage before each use and replace if teeth are worn smooth or broken.
