20D273 High-Speed Steel Chucking Reamers with Straight Shank

$37.58

Bulk orders will be discounted, please contact us.

These high-speed steel chucking reamers come in standard letter sizes. The trade letter size for each reamer indicates its compatibility with other tools that have the same trade letter size. Right-hand spiral-flute reamers draw chips up out of the hole and are used for reaming blind holes that do not continue all the way through the workpiece. Spiral-flute reamers leave a smoother finish on the hole than straight-flute reamers. 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.
