Metric carbide chucking reamers come in standard sizes expressed in millimeters. Straight-flute reamers push chips forward into a hole as they enlarge it to an exact size for a precise fit when installing fasteners or other parts. They are the most commonly used style of reamer. These chucking reamers are made from carbide steel and have a bright finish that is unaffected when their cutting edges are resharpened. The reamers' straight shank 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.
