Apex 12051 Round File 0.375 in Diameter Second Cut

Product Description

The APEX 12051 is a single-cut round file designed for smoothing, deburring, and enlarging circular openings in metal, pipe, and conduit. Measuring 10 inches in length with a 0.375-inch diameter, it features a second-cut tooth pattern that removes material at a moderate rate while leaving a reasonably smooth surface finish. The file tapers slightly toward the point, making it well-suited for working in confined spaces or refining the inside edges of holes. Constructed from steel with a hard-stamped marking style, this file is built for repeated use in trade and shop environments. Electricians, plumbers, HVAC technicians, and pipefitters commonly reach for this style of file when dressing conduit ends, pipe cuts, or drilled openings.

This round file is used in both residential and commercial settings wherever precise material removal is needed on circular or curved surfaces. It is a standard hand tool for finishing rough cuts in metal tubing, conduit, sheet metal knockouts, and similar applications. The second-cut designation makes it appropriate for general-purpose work where a mill-bastard cut would be too aggressive and a smooth cut would be too slow. Minimum order quantity is 12 units, making it practical for shop stocking or contractor supply orders.

Installation Notes

Always fit this file with a properly sized handle before use to prevent injury from the tang. Secure the workpiece in a vise or clamp before filing to maintain control and accuracy.
