This precision holder is adjustable to accurately align the cutting tool with the workpiece. The cutting tool is mounted directly in the tool head or in a bushing supplied with the holder, which can be machined to accept various size tool shanks. Rugged construction is designed to take the strain of heavy production runs. Available in long and short shank lengths.
