Product Description

The WILLIAMS COMFORT PRODUCTS 1-143-04-1-0 is a 4-inch bastard-cut mill file rated at 53 teeth per inch (TPI). Mill files in this cut grade are standard hand tools used across HVAC, plumbing, electrical, and general mechanical trades for deburring, sharpening, and dressing metal edges. The bastard cut sits between coarse and second-cut grades, making it a versatile choice for moderate stock removal on ferrous and non-ferrous metals. At 0.062 pounds, this file is a lightweight, single-use hand tool suited for field and shop work alike.

This mill file is appropriate for a wide range of trade applications including deburring pipe ends, dressing burrs from conduit cuts, cleaning up sheet metal edges, and sharpening saw blades or tool edges on the job. Its compact 4-inch length makes it well suited for tight-access work and toolbox portability. HVAC technicians, pipefitters, plumbers, and electricians commonly keep a mill file in this size range for everyday finishing and prep tasks during installation or service calls.
