Mornajina ‎5 Packs 5 Inch Indestructible disc for Grinder, Indestructible Disc 2.2 for Angle Grinder 7/8" (Model 125), Cutting Discs for Smooth Cutting, Chamfering, Grinding of All Materials (Green)

Last longer than standard cutting disc

Basically, you can just leave this one on and cut anything.If something major happens, put another one on. Got cut cut.

I purchased this type of wheel for an unusual purpose which is landscaping and garden use, specifically for cutting down large zebra grass and transplanting. Zebra grass has a nasty base of old stems from prior seasons, this stuff is like cutting wood literally like cutting a 3/8 inch hardwood dowel with some even larger. I mounted the wheel on a cordless angle grinder 4 1/2 or 5 inch and use the edge only like a cutoff wheel. it zips through the stalks like butter and does not tend to kick back like a saw blade, it does not rip into the stalks just quickly grind/cuts with relative safety. I am 100% satisfied with these wheels however I admit I have not tried them on steel.

Built doors on metal building cut over 100 feet of corrugated metal with one blade all radius cuts

Advertise as cutting metal quickly. cuts metal very slowly. Great for cutting cardboard.

I've found the Mornajina discs to offer reasonable quality, especially considering their low price. I've used them on both aluminum and steel, and the cutting speed and disk life seem comparable to more expensive brands. Overall, they're a cost-effective option for various cutting and grinding tasks.

Didn’t last at all I was cutting copper and aluminum…. Didn’t eleven get to and steel…. Save you money

These blades are a good idea, but these only cut metal one time then they're done....
