This product came apart in the first 15 minutes of use. Paid for quality! It is not!

Didn't know they had these around for the grinder. Usually it's not that tough taking the OEM nut off by turning the disc counter but once in awhile it's a pain and I hate using the wrench. This thing is quick, beefy and fantastic. Looks and feels like quality built. Definitely need to get one for each of the grinders now. Priced on the higher side but I don't think you'll get the same quality with the others.

I've already purchased 4 of these and they are awesome. no more having to struggle with stuck lock nuts and using a spanner. well worth it for those who swap angle grinder blades frequently.

Use on my 5 inch angle grinder and it works great. Very simple to get on and off. A bit bulky but has never been an issue for my applications. I use a dust collector on my Bosch angle grinder. The Bosch dust collector is bulky making taking on and off the OEM flange almost impossible. This solves that problem. Going to buy a second one for my other angle grinder!
