Product Description
Can be mounted directly on 3/6 slot rotary tables or on a base plate when the rotary table has 3/6 or 4/8 T-slots
Base plates are designed for use with all rotary tables and other devices where back mounting chucks cannot be used
These chucks can also be mounted to a rough machined backplate, but will require machining of bolt hole patterns and projections for finished assembly
