Sherline 3 Jaw Chuck Pin Jaw Set 1140

3 Jaw Chuck Pin Jaw Set

PLEASE NOTE – THESE ARE THE PIN JAWS FOR A CHUCK, THE CHUCK IS SOLD SEPARATELY AND IS NOT INCLUDED

Each year our machines and accessories are being purchased for use in fields and areas other than their intended use. One of these areas is laser engraving.

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.

Set Includes:

Each Pin Jaw set includes (3) hardened jaws (P/N 11414P), and (3) sets of each of the following lengths of 1/8″ hardened steel dowel pins: 3/4″ (P/N 11526), 1″ (P/N 11524), & 1-1/4″ (P/N 11416). These pins can be changed to give you a longer gripping area.

You may purchase these jaws to fit an existing Sherline 3-Jaw Chuck, or you can order a new chuck with the jaws installed.

These jaws can be reversed so the pin can be on the inside (standard relationship) or the outside. This allows for a larger clamping diameter range. With the jaws mounted in their standard relationship, the smallest O.D. that can be held is .226″. Keep in mind that the pins needs to be towards the center of the chuck. The smallest I.D. that can be held is .476″. The T.I.R. of these pins is .006 or less.

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.

We recently improved the design of the pin jaws. The hole that holds the pin now goes all the way through each jaw so you can easily knock out any broken pins.
