The Crescent Nicholson single-cut, bastard-cut angled lathe files are ideal for filing down significant amounts of wood or soft metals from a lathe-turned object. The bastard-cut coarseness design removes material aggressively, cutting faster than a regular mill file, but leaves a smoother finish because of the single-cut pattern. The rectangular shape and large size of these files are perfect for large-scale jobs where precision is key.
