The WILLIAMS COMFORT PRODUCTS 1-106-10-1-0 is a 10-inch round file with an Oberg cut pattern, designed for precise material removal in metalworking, fabrication, and mechanical service applications. The Oberg cut geometry delivers consistent chip clearance and controlled stock removal, making it well suited for enlarging holes, smoothing curved surfaces, and dressing internal radii on ferrous and non-ferrous materials. At 0.498 pounds, the file is light enough for extended hand use without fatigue. Technicians in HVAC, plumbing, electrical, and general mechanical trades reach for this style of file when fitting conduit knockouts, deburring copper tubing, or cleaning burrs from drilled or punched openings.
This round file is appropriate for both residential and light commercial service work. It fits naturally into a field technician's toolkit for tasks that require shaping or finishing round openings, smoothing weld seams on round stock, or refining threads and ports during installation or repair. The 10-inch length provides adequate reach for most bench and in-place filing tasks encountered during trade service calls.
Designed as a general-purpose round file for use across metalworking, HVAC, plumbing, and electrical trade applications requiring internal or curved surface finishing.
A licensed or qualified tradesperson should always wear appropriate personal protective equipment, including safety glasses and gloves, when using hand files. Ensure the workpiece is securely clamped or fixtured before filing to prevent movement and injury. Inspect the file for cracks or missing teeth before use and always fit a proper handle to prevent hand injury from the tang. File in forward strokes with controlled pressure and lift on the return stroke to preserve cut geometry.
