Absolute top quality chucks made for high precision work.
These South Bend lathe chucks are amongst the best available on the market.
Walking into the factory that makes these South Bend Lathe chucks, one would be amazed at the plethora of high tech testing equipment made by some of the most respected names in the world.
This includes these high-precision cast-iron 3-Jaw scroll chucks with 2-piece jaws and plain backs with a D1-6 camlock mount.
Direct-mount chucks require less initial setup time because the machinist is not required to machine a back plate to fit the chuck.
The SB1220 comes supplied with all the hardware for mounting on your lathe.
Made with tight tolerances to satisfy the most demanding machinists out there!
The instruction sheet was written by our U.S. based Technical Documentation Department and is packed with useful information.
Like all South Bend products, it comes with a 2-year warranty which covers parts and assures the unit is free from factory defects.
The South Bend Customer Service and Technical Support Teams are U.S. based. Parts and accessories for the chuck are available on-line and shipped from the South Bend parts warehouse in Springfield, MO.
