This high quality pin vise has a nut shaped head and knurled handle making it easy to tighten down by hand or with a wrench. The square head also keeps the tool from rolling around a bench. This pin vise has well-machined threads and tapers for a smooth feel and even closure.
The thru-hole handle can be chucked into a bench motor or lathe to hold a long screw or rod in the collet.
Comes with two steel collets, which are keyed to keep them from rotating in the tool. The second collet can be stored securely in the back of the handle when not in use.
Handle length including collet: 4" (100mm)
Thru hole in collet handle: .25" (6mm)
Collets will hold most round parts from .112" (3mm) and smaller.
