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.
