Secure jaws to a CNC lathe chuck with industry standard 1.5 mm × 60° serrations or wider 3 mm × 60° serrations.

Mount these chucks to a lathe's spindle to hold round workpieces. Also known as scroll chucks, they are self centering—all jaws move in unison, centering the workpiece as they close. 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. You can run them at higher speeds than cast iron chucks, and they’ll last longer. Use the included lathe chuck wrench to open and close the jaws.

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.
