Pin Jaws


We designed our Pin Jaws specifically for laser engraving rings and other similar parts. These jaws are not designed for machining parts or other uses that require more than finger tight closing pressure to hold the part in the chuck. Round parts can be held from the inside with just finger-tight grip of the pins while the outside is laser marked. The jaws will work in any of our 3-Jaw Chucks. Each set includes 3 3/4″, 1″ and 1-1/4″ dowel pins.

SKU: 1140.
