Nicholson 00070NN Flat File 12 Inches Double Cut Bastard

Product Description

The NICHOLSON 00070NN is a 12-inch American-pattern flat file designed for metal shaping, deburring, and surface finishing in professional trade and shop environments. It features a double cut, bastard cut tooth pattern that removes material efficiently on flat surfaces. The file measures 12 inches in overall length, 1 inch in width, and 0.2 inches in thickness, with a tang end for use with a compatible file handle. Weighing 0.93 pounds, it is built for hand filing tasks performed by machinists, pipefitters, plumbers, HVAC technicians, and maintenance professionals who require consistent stock removal on metal workpieces.

This flat file is suited for general-purpose filing on aluminum and other soft to medium-hardness metals. The double cut pattern cuts on both the push and cross strokes, making it effective for rapid material removal and surface cleanup on flat workpieces, flanges, pipe ends, brackets, and fittings. It is a standard hand tool for trade shops, field service kits, and maintenance facilities where precise manual filing is part of routine work.

Installation Notes

Installation of a file handle is recommended before use to protect the hand from the tang. Secure the workpiece in a vise or clamp before filing to prevent movement and ensure accurate material removal. Always file with controlled strokes and inspect the file teeth periodically to clear metal filings with a file card brush. No power tools, special codes, or permits are required for hand file use.
