20G990 High-Speed Steel Chucking Reamers with Straight Shank

$27.39

Bulk orders will be discounted, please contact us.

Left-hand spiral-flute high-speed steel 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. The reamers’ bright finish is unaffected when their cutting edges are resharpened. Reamers are used to enlarge a hole to an exact size for a precise fit when installing fasteners or other parts. These high-speed steel reamers have a straight shank that mounts to the chuck of a drill press or similar machining tool.
