Nicholson 21846NN Round File 6 Inches Single Cut Bastard

Product Description

The NICHOLSON 21846NN is a 6-inch American-pattern round file designed for material removal, deburring, and shaping tasks in machining and general metalworking applications. This single-cut file features a bastard-cut tooth pattern, which provides a balance between aggressive stock removal and a reasonably smooth finish. The round cross-section makes it well suited for enlarging holes, filing curved interior surfaces, and working in tight radii. At 0.09 pounds, it is a lightweight hand tool. The file includes a tang end for use with a standard file handle. It is not flexible, making it appropriate for controlled, straight-stroke filing work performed by machinists, maintenance technicians, and skilled tradespeople.

This file fits common applications in machine shops, maintenance and repair operations, and fabrication environments. The round profile is particularly useful when working on pipe ends, conduit openings, and circular cutouts in metal stock. The bastard cut is a standard choice for initial shaping passes before moving to a finer-cut file for finishing. The 5-7/16-inch length of cut delivers usable filing surface across nearly the full length of the 6-inch body. This file is sold individually and is handled by the user with a separately sourced file handle fitted to the tang.

Compatibility

Designed as an American-pattern round file for general machining and metalworking use. Accepts any standard file handle sized to fit a tang-style file.

Installation Notes

Always fit a proper file handle to the tang before use to prevent hand injury from an exposed tang during filing strokes. Secure the workpiece in a vise or clamp before filing to maintain control and consistent stroke angle. File handles are sold separately and must be sized to match the tang dimensions. Inspect the file for cracks or missing teeth before each use and replace if damaged.
