The Sherline Top Jaws for Laser 3-Jaw Pin Chuck (Set of 3) are specifically engineered for laser marking applications, accommodating parts with diameters ranging from 0.66 inches to 6 inches. These top jaws are compatible with 3-jaw chucks produced after 2014 and are designed to hold parts securely with finger-tight pressure, making them ideal for precise laser marking tasks. The jaws feature four pinhole locations that accommodate 3/16-inch hard-steel dowel pins, allowing for versatile positioning of parts during the marking process. They attach to the master jaws using a socket head cap screw, ensuring a stable and reliable setup. These jaws are not intended for machining or applications requiring significant clamping force. Note: Chucks manufactured prior to 2014 require custom grinding of each jaw to ensure proper fitment.
