Push a button to clamp or release multiple workpieces on your milling machine or drill press. To create a high-density setup, mount these fixtures and join them together using two connector bushings (sold separately) for each fixture you want to add. These fixtures have a through hole for clamping long workpieces.

Air or hydraulic pressure opens and closes the collets (not included). A good choice for heavy machining, these fixtures provide a tighter hold than you can achieve with manual power. You can operate multiple fixtures with a single valve (not included) and two hoses—one for supply and one for return. All are double acting, so they need air or hydraulic pressure both to open and close. This means that the workpiece stays locked in place even if you lose pressure. Clamping force depends on the air or hydraulic pressure of your system.
