Crescent® Nicholson 8" Round Bastard Cut File is a high carbon steel file with a red handle. The round single-cut bastard file features a circular design with teeth all the way around. These files can be used to file circular openings or concave surfaces. The single-cut construction provides light removal of material and slightly smoother edges. The slight taper in width towards the file's point creates ease of access in slots. Crafted from metal, the file's construction offers strength and durability.
