Its rectangular profile provides consistent contact along straight edges, making it a reliable tool for metalworking tasks in fabrication, maintenance, and tool-sharpening applications. Two square edges allow the technician to cut grooves that match the file's width precisely, and the body tapers slightly in width toward the tip to improve access in narrow slots and confined work areas.\u003c\/p\u003e\u003cp\u003eThis bastard mill file is suited for trade and industrial settings where accurate sharpening and surface finishing are required. It is commonly used by machinists, millwrights, maintenance technicians, and metalworkers who need a dependable single-cut file for controlled, smooth stock removal on ferrous and non-ferrous metals. The single-cut tooth pattern delivers a cleaner finish with each stroke compared to double-cut configurations, making it appropriate for finishing passes and fine-tuning cutting edges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-inch single-cut bastard mill pattern for controlled material removal\u003c\/li\u003e\n\u003cli\u003eRectangular profile for smoothing and sharpening flat, straight surfaces\u003c\/li\u003e\n\u003cli\u003eTwo square edges enable consistent-width groove cutting\u003c\/li\u003e\n\u003cli\u003eSlight taper in width toward the tip improves reach in slots and narrow openings\u003c\/li\u003e\n\u003cli\u003eSuitable for draw filing and metal finishing applications\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of 6 units per case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard bastard mill file suitable for sharpening mill saws, circular saws, and general metalworking and finishing tasks on flat or slotted surfaces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways secure the workpiece in a vise before filing to maintain control and prevent injury.
