445N77 High-Speed Steel Chucking Reamers with Straight Shank

$34.49

Bulk orders will be discounted, please contact us.

Oversized high-speed steel chucking reamers are slightly larger than a standard size. This helps ensure a loose fit when inserting a standard-size item in a hole made by the tool. 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 high-speed 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.
