Useful for small VMCs and multiplex turning machines, DR (ER) 32 Shorty collet chucks from Command Tooling Systems are available in 40 V and 50 V styles to ANSI V and 40 BT for tool shank diameters ranging from 0.079" to 0.787".
The units feature a near flush collet nut that virtually eliminates tool overhang, thus improving accuracy and tool rigidity, the company says. Collet pockets are concentric to the spindle taper to 0.0002" TIR, placing the tool on the spindle center line; taper tolerances are AT3 or better.
