Bulk orders will be discounted, please contact us.

These carbide chucking reamers come in sizes that fall between standard trade sizes, and their sizes are expressed in decimal inches from 0.0030" to 0.2170". 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 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.
