LAOA | LAOA 8" 5PCS File Set Triangular/Flat/Semicircular/Square/Round Metal Files T12 Steel Hand Tools for Deburring Grinding

OverviewThe LAOA 8-inch medium-cut file 5-piece set includes five essential file types: triangular, flat, semicircular, square, and round — one set covers a wide range of metal, wood, and plastic workpiece finishing and grinding needs. Made from integral forged T12 high-carbon tool steel with quenching heat treatment, the files achieve a hardness of HRC 62-67°, with sharp and uniform teeth for high cutting efficiency, excellent wear resistance, and long service life. The handle is made of TPR+PP composite material with an ergonomic non-slip design for comfortable grip, reducing hand fatigue during extended use. A hanging hole at the handle end facilitates easy storage.Specifications & Applications by Model1.
