Boring Bars

The Standard Boring Bar is made of 3/4” diameter by 19" long steel. It is used to hold the optional straight cutter holder with swivel tip and 3/16” sq. cutter. Inserting the holder into one end of the boring bar positions it straight out the end of the Boring Bar, inserting it into the other end presents it at a 45° angle to the boring bar.

The Jumbo Boring Bar measures 1-1/8” in diameter by 22" and allows for extending the tool up to 18” off the tool rest. The Jumbo Boring Bar has a hole in only one end.
