Of medium coarseness, the second-cut TEKTON 10 in. Mill File is a versatile shop file for working with metal, plastic, and wood. Made to remove material at a slower rate with each stroke, the single-cut teeth create a smooth finish when you're deburring, shaping, and sharpening. The tapered rectangular profile finishes lathe work, smooths edges, and sharpens saw teeth and blades. A large, contoured poly handle gives you a comfortable, nonslip grip for controlled speed and pressure with every stroke.
