Unfortunately these have been unusable for me because they did not come with the collars. Please don’t everything that I saw it was a kit. Not just the little box. I understand that someone may need to replace it, but it would’ve made a whole lot more sense to me if they would have made it a kit that included everything needed to make these work. I was so frustrated when I receive them that I never even went back to order the collars. I basically spent money for nothing at this point.

Be careful when ordering. They are useless without the stop collars. Available at additional cost of around twenty dollars for each size.

I think this will be a handy little gadget when working with endmills but with 1/8 shank vee bits are too short for this application. The shank of the bit doesn't protrude far enough above the collar to be able to insert it into the collet. I haven't tried it yet but I think it will help considerably with changing between endmills for roughing and finishing cuts.
