The Nut Cupper – because nobody likes a loose nut.
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!
Thanks, William! We appreciate the 5 star review.
This nut cupper was exactly what I was looking for! Perfect for the job at hand!
Hell yeah! Thanks for the 5 star review on The Nut Cupper.
Awesome and convenient addition to me angle grinder. Great communication and customer service.
Wrong size for my grinder even though it was advertised for it.
Please email support @ tmrcustoms . com and we'll replace it free of charge. It's tough to keep up with all the different Grinders on the market! Thanks.
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.
Thanks, Steven! Stoked to hear you are happy with The Nut Cupper.
