The Crescent Nicholson® 21853 Round Bastard File is a professional-grade tool designed for precision shaping, smoothing, and deburring of circular openings and concave surfaces. With its 8-inch length and single-cut bastard teeth, this American-pattern file delivers controlled material removal and a smoother finish, making it ideal for machinists, metalworkers, woodworkers, and DIYers alike.

Crafted from high-quality carbon steel, this file features a round profile with teeth cut all the way around, allowing it to reach into areas that flat or rectangular files cannot. Its slightly tapered design toward the tip enhances accessibility in tight slots and curved contours, while the safe point helps reduce the risk of accidental injury during use.
