Jet Tools' 10 in. Square Smooth-Cut Metal File is constructed from hardened steel to provide durability and consistent performance in workshop and industrial environments. The fine tooth geometry reduces surface roughness while maintaining control, making it ideal for final-stage finishing and precision work. Commonly used by machinists, toolmakers, and maintenance professionals, this square file supports accurate contouring, edge refinement, and internal shaping where clean, smooth results are required.
