Nicholson 21715 Round Bastard Cut File 8 Inches

Product Description

The NICHOLSON 21715 is an 8-inch round American-pattern file designed for material removal, deburring, and shaping on metal, wood, and plastic surfaces. It features a single cut tooth pattern with a bastard cut coarseness, making it well suited for moderate stock removal and surface finishing in a single pass. The 5/16-inch diameter profile fits into tight grooves, holes, and rounded contours where flat files cannot reach. An ergonomic handle is included, giving the technician a secure grip during controlled strokes. Weighing 0.2 pounds, this file is light enough for extended use without hand fatigue.

This file is used across a range of trade applications including HVAC, plumbing, electrical, and general mechanical work. Common uses include dressing burrs on cut pipe, enlarging or smoothing conduit knockouts, cleaning up threaded fittings, and shaping gasket seats. The round profile and bastard cut coarseness make it a go-to hand tool for field technicians who need consistent material removal without power tools. It is equally at home in a shop environment or on a job site.

Installation Notes

No power source or lockout procedure is required for hand file use. Always inspect the handle for cracks or looseness before use, as a loose tang can cause injury. Use smooth, controlled forward strokes and lift the file on the return stroke to preserve tooth life. Eye protection is recommended when filing metal to guard against dislodged chips.
