    5C Collet to Lathe Chuck Adapters

    Image of Product. Front orientation. Contains Annotated. Lathe Chuck Collet Adapters. 5C Collet to Lathe Chuck Adapters.
    No need to break down a collet set up when a workpiece doesn't fit a 5C collet. Install one of these lathe chuck adapters in your 5C collet chuck or holder and its three jaws will securely grasp the workpiece. These chuck adapters are self centering—all three jaws move in unison, centering the workpiece as they close. Use the included lathe chuck wrench to open and close the jaws.

    Lathe Spindle Stops

    Image of Product. Front orientation. Contains Annotated. Lathe Spindle Stops.
    Position workpieces in the same spot every time to quicken setup, improve repeatability, and cut down on scrap. These stops create a repeatable position within your lathe spindle for clamping parts loaded through a chuck or collet. They fit a range of spindle bore diameters—the jaws expand outward for a secure, self-centering fit. To lock these stops in place, expand them with just a few turns of the T-handle wrench. They can be used on both CNC and manual lathes.
