The Nicholson 05307N is a 16-inch (406mm) half round bastard cut file, built for versatile material removal on flat, curved, and contoured surfaces. The half round profile allows you to work both flat faces and concave shapes with a single tool, while the bastard cut provides an efficient balance of stock removal and surface finish.
Nicholson files are trusted by machinists, fabricators, and tradespeople for consistent cut quality and long-lasting performance. This file is well suited for deburring, shaping, and smoothing metal workpieces in workshop, industrial, and MRO applications.
