Williams Comfort Products 1-143-12-2-0 Mill File 12 in

Product Description

The WILLIAMS COMFORT PRODUCTS 1-143-12-2-0 is a 12-inch mill file with a second cut tooth pattern rated at 40 teeth per inch (TPI). Mill files are single-cut flat files used for draw-filing, deburring, and finish work on metal surfaces. The second cut grade sits between bastard and smooth, removing material efficiently while leaving a relatively clean surface. At 0.672 pounds, this file is light enough for extended hand use. It is a standard hand tool used by HVAC technicians, pipefitters, plumbers, and electricians for cleaning burrs from cut pipe, conduit, and sheet metal edges.

This mill file is suited for general trade shop and field use wherever metal edge preparation is needed. Common applications include cleaning threaded pipe ends, smoothing sheet metal flanges, deburring conduit cuts, and dressing tool edges. The 12-inch length provides good leverage for draw-filing on flat stock and pipe surfaces. It is sold as an individual unit and is appropriate for any trade professional who performs regular metalwork as part of installation or service operations.

Key Features

• 12-inch file length for adequate leverage on flat and curved metal surfaces
• Second cut tooth pattern at 40 TPI balances stock removal with surface finish quality
• Lightweight at 0.672 pounds for reduced hand fatigue during extended use
• Mill file profile suitable for draw-filing, deburring, and edge dressing
• Single-cut tooth geometry produces clean, consistent strokes on metal

Compatibility

Designed as a general-purpose hand file for use on ferrous and non-ferrous metal surfaces across HVAC, plumbing, electrical, and pipefitting applications.

Installation Notes

Mill files should always be fitted with a proper handle before use to prevent tang injuries. Work should be secured in a vise when draw-filing to maintain consistent pressure and avoid slipping. Always wear appropriate eye protection when filing metal. Files are cutting tools and should not be used on surfaces harder than the file itself, as this will damage the teeth.
