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.

Boring Rings for Machinable Lathe Chuck Jaws
Hold machinable lathe chuck jaws in place during machining to make accurate cuts, ensuring the jaws will securely grip your workpiece. These boring rings pin the jaws down, creating the same clamping pressure you’ll use on your workpiece, which keeps the jaws from warping or deforming while they hold your workpiece.
Designed with an open center, these rings leave room for you to machine the center of your jaws. Fit the pins on the rings to the screw holes on your jaws, then clamp the jaws down to hold the ring in place. Once the ring is attached, rotate it to adjust the jaws to the center of their stroke before machining.
Match standard rings to your lathe chuck’s diameter for machining the center of your jaws. Line them up with your jaws by sliding the pins along their curved tracks.
Adjustable rings fit a range of lathe chuck diameters. The pins are mounted to straight tracks—slide them in and out of the ring to adjust the diameter. They are also reversible, which allows you to machine both the inside and outside of your jaws. When the pin screws are outside the ring, you can machine the center of your jaws. Flip them around to the center of the ring to machine the outside of your jaws.
