I absolutely love this tool. Great quality and it is very convenient having it on the grinder for switching between different wheels while working on equipment and products. Thank you TMR!

- SSSteven S.Verified BuyerI recommend this productRated 5 out of 5 stars3 months agoGreat product For an aggravating problem
We received the nut cupper and immediately put it on our grinder. We constantly change the brushes and grinding wheels on our grinder and have lost many retaining collars. This has saved us time, money and aggravation.

- GJGordon J.Verified BuyerI recommend this productRated 5 out of 5 stars4 months agoThe "Nut Cupper" - what a great idea !
such a simple device, but it will avoid losing the lock nut when I use a screw on flap disc. Are you going to make one for other grinders, like Bauer?
Was this helpful?TMR Customs USA4 months agoYes, we can definitely make one for a Bauer grinder. We just need to know the thread specs of the handle.
