Universal Chuck Rotary Adapter - 20oz, 30oz, and 40oz Non-Threaded Tumbler

So far so good. I’ll have to see if they have one for the regular chucks.

Quick delivery | Exceptional Quality

Quick delivery and exceptional quality are what you can expect when you order from MKR supply. I will continue to order laser tools and supplies from a trusted maker in the business. A+

A bit tight on my rotary jaws, had to customize to fit and rotate true. Also had to add tape in groove to make rubber washed snug enough to hold 20oz tumbler from walking loose. But overall descent product just one size doesn't fit all.
