Let me tell you, as someone who constantly misplaces small tools, this grinder nut kit has been a lifesaver. The first time I used it was when I couldn't find the original wrench for my DeWalt grinder - typical ADHD moment. The threaded nuts fit perfectly, and the included wrench actually feels sturdier than the one that came with my tool.

I've used these nuts with both cutting and grinding wheels on my 4-1/2" grinder, and they hold up really well. The carbon steel construction means they don't strip easily like some cheaper alternatives I've tried. What surprised me most was how well-oiled they arrived - each piece individually packaged in this neat little box that's now living in my toolbox drawer.

One thing to note: these do have indexing flats, which didn't match my buddy's Skil grinder. We had to modify them slightly with a file to make them work. But for my DeWalt? Perfect fit right out of the box. The outer nuts especially grip the discs securely without any wobble during operation.

The value is fantastic - having multiple spares means I can keep sets in different places around my workshop. No more frantic searching when I need to change discs mid-project! Just wish they made the wrench slot a bit narrower to fit all tool holders better.
