General's Double End Pin Vise helps to reclaim precious time that is normally spent switching between tool attachments or searching for drill bits in a crowded tool box. Each end of this Pin Vise features a reversible collet for holding your favorite drill bits, taps and reamers. Now you can drill a small hole with one end of the tool, then flip to the other end for quick deburring or reaming. In addition, the Double End Pin Vise features a knurled body for a comfortable grip and a hollow interior for use with long wire or rods.
