Williams Comfort Products 1-143-12-3-0 Mill File 12 in

Product Description

The WILLIAMS COMFORT PRODUCTS 1-143-12-3-0 is a 12-inch smooth-cut mill file rated at 48 teeth per inch (TPI). Mill files of this cut grade are used for fine finishing, deburring, and draw-filing on metal surfaces where a clean, smooth finish is required. At 0.672 pounds, the file is light enough for extended single-hand use while still offering the mass needed for controlled strokes on hardened or mild steel stock. Licensed tradespeople and skilled technicians reach for smooth-cut files when the final pass on a workpiece demands minimal tooth marks and tight surface tolerances.

This file is suited for bench work, field service, and maintenance applications across HVAC, plumbing, electrical, and general mechanical trades. Common uses include cleaning burrs from pipe ends, dressing valve seats, smoothing bracket edges after grinding, and refining contact surfaces on mechanical components. The 12-inch length provides good leverage for full-stroke filing on larger workpiece sections while remaining manageable in confined equipment cabinets or utility rooms.

Key Features

• 12-inch length for full-stroke filing coverage on standard workpiece sizes
• Smooth cut at 48 TPI for fine finishing and minimal surface scarring
• Lightweight at 0.672 pounds for extended use without fatigue
• Mill file profile suitable for flat and slightly convex surfaces
• Sold individually (each unit), no minimum quantity requirement beyond one

Compatibility

Designed as a general-purpose smooth-cut mill file for use on mild steel, hardened steel, and similar metal surfaces in trade and maintenance applications.

Installation Notes

Always fit a proper handle to the tang before use to prevent hand injuries during filing strokes. Secure the workpiece in a vise or with appropriate clamps before beginning work. Clean the file with a file card regularly during use to prevent pinning, which can scratch the workpiece surface. Inspect the file for cracks or broken teeth before each use and replace if damaged.
