Machinable Lathe Chuck Jaws
Machine these jaws to fit the curves and edges of your unique workpiece for a tighter hold and more stability than standard hardened jaws. They have industry standard 1.5 mm x 60° serrations, which mount to most CNC lathe chucks from Kitagawa, LMC, Samchully, Seoam, and Auto Strong. Attach to your chuck with jaw nuts (not included). For the tightest fit to your workpiece, use boring rings to hold your jaws in place while machining.
Pointed jaws provide three points of contact on the workpiece. They are the best choice for most custom workholding.
Full-grip jaws surround the workpiece for maximum grip from every angle, ensuring an exact fit on thin or intricate parts.
Aluminum jaws are lighter in weight than steel and can be turned at higher speeds with less wear on your machine.
Steel jaws are more durable than aluminum. For repeated use, harden them after machining.
