Nicholson 16761NN Warding File 8 in Double Cut Bastard

Product Description

The NICHOLSON 16761NN is an American-pattern warding file designed for precise key filing and slot work. It features a double-cut, bastard-coarseness tooth pattern ground across an 8-inch cutting length, making it effective for fast material removal on soft metals and ferrous stock. At 25/32 inches wide and 3/32 inches thick, the narrow, thin profile fits into tight keyways, slots, and restricted filing areas where wider files cannot reach. A tang end accepts a standard file handle. Licensed locksmiths, machinists, HVAC technicians, and maintenance tradespeople keep this file in rotation for lockset and key modification tasks.

This file is sized and shaped for key and warding work in residential and commercial locksmithing applications. The narrow warding profile allows access to the internal ward slots of lock bodies and the bitting channels of key blanks. It is also used in light metalworking and maintenance settings where a controlled, narrow double-cut surface is needed to true up slots or remove burrs from ferrous and non-ferrous metal parts. The file is sold individually and does not include a handle.

Installation Notes

A file handle should be fitted to the tang before use to prevent hand injury from the exposed point. Files are push-cut tools and should not be dragged back under pressure on the return stroke, as this dulls the teeth prematurely. Keep the file clean with a file card or brush to prevent pinning, which can scratch the workpiece. Files should never be used on hardened steel surfaces harder than the file itself, as this will damage the cutting teeth.
