The Rex cut Sigma Z is the best grinding disk I have ever used. I have been Welding for 20+ years and have used countless brands of grinding disks and nothing eats steel and lasts like like sigma z nothing...

Rex-Cut Grinding Wheels are the best, honestly. If an abrasive salesman reaches out, I tell them they can't match my current choice. Once I tell them, they either don't know about them or they agree! The blending/cotton polishing grinding wheels are super handy as well. When I work with stainless steel nothing comes close to those two products. They have an absolute powerhouse of products!

I can say for sure that the material removing capabilities of Sigma Green Max has cut down expenses by at least 50 percent due to the longevity of the product, which keeps me from having to constantly buy flap wheels or grinding stones. But the biggest thing is the frustration factor. I'm less fatigued at the end of the day, I spend less time changing out equipment, and I'm protecting my health. You can't put a price on that.

I had lost faith in grinding discs, until your sigma green discs opened my eyes to new possibilities! These discs remove material faster than any disc I’ve used in the last 15 years. Weather its fabricating frames, or sculpting voodoo dolls they haven’t let me down. There really isn’t any other option!
