Mango giratorio con collar

I love this easily controlled way to set a smooth stone. I only use smooth cabochons in my worki a dvtbis meetings much faster . I wish they’d make a bigger one for larger stones. I’d buy it in a minute.

This statement in the description is incorrect: “Chuck opens from 0 to .089" (0 to 2.3 mm).” The collet only accommodates 3/32” shanks. I would like to return this item.
