The VM100 T - Bar Allen Key operated chuck allows for one handed tightening along with tremendous gripping power provided by the 4.5 to 1 ratio of the scroll.
Keyed chucks cannot be beaten when it comes to holding power. The totally enclosed back assures consistent, smooth action by preventing dust and debris from getting into the scroll and moving parts of the chuck.
The backing lid is also indexed for those wood turners who do not have an indexing facility on their lathes. The VM100's compact size makes it ideal for use on 300mm (12") capacity lathes or smaller.
