Left-hand spiral-flute carbide chucking reamers push chips into the hole as they enter a workpiece. They are used for reaming through holes, and they typically leave a finer finish on the hole than right-hand spiral-flute chucking reamers and straight-flute chucking reamers. These carbide reamers have a TiAlN finish that withstands high temperatures and protects the reamers from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. A TiAlN finish can be an economical alternative to an AlCrN finish. Reamers are used to enlarge a hole to an exact size for a precise fit when installing fasteners or other parts. These reamers have a straight shank that mounts to the chuck of a drill press or similar machining tool.
