Right-hand spiral-flute carbide chucking reamers pull chips out of the hole as they enter the workpiece, which helps prevent damage to the tool and the workpiece. They are used for reaming blind holes and are suitable for applications with interrupted cuts, such as keyways. Spiral-flute reamers leave a smoother finish on the hole than straight-flute chucking reamers. The bright finish on these carbide chucking reamers is unaffected when the reamers' cutting edges are resharpened. These reamers enlarge a hole to an exact size for a precise fit when installing fasteners or other parts, and they have a straight shank that mounts to the chuck of a drill press or similar machining tool. Solid carbide chucking reamers provide excellent wear resistance when machining the toughest materials, such as cast iron, nonferrous alloys, and stainless steel. These reamers have a straight shank that mounts to the chuck of a drill press or similar machining tool. Chucking reamers, sometimes called machine reamers, enlarge or finish an existing hole to an exact tolerance or size for a precise fit when installing fasteners or other parts. They usually have a 45? chamfer on the cutting edge to help ensure accuracy as the reamer enters the hole during metalworking tasks. This listing is for each.
