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.

Adjust each jaw on these chucks separately to hold rectangular or odd-shaped workpieces. Also known as independent chucks, they have four jaws that each have their own adjustment screw. For quicker setups, you can also remove two jaws and clamp with the remaining two. All jaws are reversible, so you can install them for either an inside or an outside grip. Use the included wrench to move them in or out. Made of forged steel, these chucks are strong and wear resistant, so they maintain their shape even with continuous use. They’re often used for precision machining. They last longer than cast iron chucks, and you can run them at higher speeds.

Use high-pressure grease to improve grip and prolong the life of your chuck.

You’ll need a mounting plate to attach the chuck to your lathe. Choose a mounting plate that matches the diameter of the lathe chuck, your lathe’s spindle type, and the spindle OD.

Precise and powerful clamping for high speed, heavy duty CNC turning. These chucks connect to your CNC lathe’s hydraulic system to open and close the jaws—no more cranking with a chuck jaw wrench. To mount the chucks to your lathe, machine the included blank draw nut to match the thread of your drawtube. You can use these as drop-in replacements for major machine brands such as Okuma, Mazak, Haas, Hyundai WIA, and Doosan.

These chucks are self-centering, so all the jaws move in unison to center the workpiece as they close. They come with a set of machinable jaws that you can bore to fit the curves and edges of your unique workpiece for a tighter hold and more stability than standard hardened jaws. For additional sizes and materials, see our full offering of machinable jaws.

Jaw-boring chucks reduce the time it takes to machine jaws. Instead of a separate boring ring or machined slugs that you have to position and reposition, they have a built-in adjustment ring. All you need is an L-key to fine-tune alignment once before machining. The ring moves in increments as small as 0.004”, so the jaws are machined for a tight fit to your workpiece.

A mounting plate (sold separately) is required to mount the chuck to a lathe. Select a mounting plate that matches the diameter of your lathe’s chuck and spindle OD.
