Its light weight, and with less overhang which is perfect for smaller lathe spindles. The small 1.79" body length delivers less overhang from the spindle than the larger geared Chucks - the SuperNova2 Chuck and the Nova Titan Chuck, reducing stress on smaller lathe spindles.

Note: If you don't have a NOVA Comet II Midi Lathe you cannot use this chuck. Please instead purchase the standard G3 Chuck. If your lathe is less than 14” diameter swing, please have a look at the Nova Precision Midi chuck.  If your lathe has more than 14” diameter swing, please have a look at the SuperNova2 Chuck or the NOVA Titan Chuck.
