Review on Delta Diamond Extreme 4-1/2-Inch Metal Cutting Diamond Blade: The Ultimate All-Purpose Heavy Duty Grinding & Cut Off Wheel for Rebar, Sheet Metal, Angle Iron & Stainless Steel by Jason Graham

I am a mobile workshop and property manager. I like to leave one of my cordless grinders in the off mode for quick clamps and cuts on the fly. Although cut-off wheels can cut faster, they always break when tools are stored and tool boxes are moved back and forth. I've found before that diamond blades don't cut very quickly and I wouldn't sue them for grinding. This bike has been greatly improved. More and more diamonds to cut faster. It also grinds great. It's nice to have a good wheel at the mill when I need it. Also, I feel more confident knowing the blade won't fall apart when I turn it.
