The WILLIAMS COMFORT PRODUCTS 1-230-04-1-0 is a 4-inch round bastard-cut file rated at 43 teeth per inch (TPI). Round files in this cut and size are standard hand tools used across mechanical trades for deburring, enlarging holes, smoothing curved surfaces, and sharpening chainsaw teeth or similar cutting edges. The bastard cut sits between coarse and second-cut grades, removing material efficiently while still leaving a reasonably smooth finish. At 0.02 pounds, this is a lightweight, single-use-style file suited for tight access areas and detail work in the field or shop.
This file is appropriate for use in HVAC, plumbing, electrical, and general mechanical service work wherever a small-diameter round file is needed. Common applications include cleaning up burrs on pipe ends, opening knockout slugs, smoothing notched sheet metal, and maintaining cutting tools on the job site. The compact 4-inch length makes it easy to carry in a standard tool pouch. Minimum order quantity is 10 units, making it practical for stocking in a service van or shop inventory.
Designed as a general-purpose round bastard-cut hand file compatible with standard file handles accepting 4-inch file tangs; no specific OEM system compatibility is stated by the manufacturer for this SKU.
Always seat the file tang fully into a properly sized handle before use to prevent hand injury from an exposed tang. Use smooth, consistent forward strokes and lift the file on the return stroke to preserve tooth life. Eye protection is recommended when filing metal to guard against swarf. No power tools, codes, or shutdowns are required for standard hand-file use.
