Boring Tools to Open Up Holes to Exact Size

Boring tools take a drilled hole and open it up to an exact size with a clean, round finish. A drill can only get you close, while a boring setup lets you creep up on the final dimension a few thousandths at a time. That makes them a staple in metalworking, from machining bearing bores to cleaning up worn holes on repair jobs.

Most setups start with one of the boring heads mounted on a milling machine, using a dial to offset the cutter for each pass. The head holds one of the boring bars, which come in different lengths and diameters to reach deep or small holes, including indexable styles with replaceable inserts. Boring head shanks & adapters match the head to your machine's spindle. JB Tools offers fast shipping and free shipping on orders over $99, so order your boring tools today!
