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.

Hardened Lathe Chuck Jaws
Made from hardened steel, these jaws have a long service life even when performing heavy machining such as roughing cuts. Jaws are reversible and have teeth to grip a workpiece from its outside or inside. Fits most CNC lathe chucks made by Kitagawa, LMC, Samchully, Seoam, and Auto Strong. To ensure compatibility, match your chuck's diameter, slot width, serration type, and mounting-hole center-to-center distance. Attach to your chuck with jaw nuts (not included). Each set includes three jaws.

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.

 Adjustable With Hardened Steel Parallels |
Consistently position workpieces in a three-jaw lathe chuck. These stops enable short workpieces to extend beyond the chuck's jaws, providing additional clearance. A magnetic back makes them easy to mount and remove from your chuck face.
Fixed chuck stops are a simple, consistent way to position your piece.
Adjustable chuck stops can be used with parallels or your own custom supports to position workpieces at the exact depth you need. Those that include hardened steel parallels come ready to set at various depths.

Three-Jaw Lathe Chucks
Mount to a lathe's spindle to hold round workpieces. Also known as scroll chucks, these 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.
Chuck with solid jaws comes with one set of outside jaws and one set of inside jaws.
Chucks with reversible jaws come with one set of jaws that can be installed for either an inside or outside grip.
A mounting plate (sold separately) is required to mount the chuck to a lathe. Select a mounting plate that matches the diameter of the lathe chuck and your lathe’s spindle type and spindle OD.

Economy Lathe Chucks
Choose these lathe chucks when high precision isn’t critical. Made of cast iron, they don't match up to the same tight tolerances as forged steel lathe chucks. This means they are only rated to half the maximum speed, so they may wobble at high speeds. Also known as scroll chucks, they are self-centering—all three jaws move together, centering the workpiece as they close. Use the included lathe chuck wrench to open and close the jaws. You’ll need a mounting plate (not included) to connect these chucks to your lathe.
Fixed jaw lathe chucks come with a set of inside and outside jaws.
Reversible jaw lathe chucks have one set of jaws that provide either an inside or outside grip.
High-pressure grease (sold separately) improves grip and prolongs the life of your lathe chuck.

Lathe Chuck to 5C Collet Adapters
When a job calls for a 5C collet, save time by using an adapter instead of removing your lathe chuck. The adapter fits most lathe chucks. Install a 5C collet into the adapter and secure it by turning the lock with the included hex key.

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.
