GRAFF Black Cut Off Wheels 4 1/2 Inch - Diamond Metal Cutting Disc for Angle Grinder 4.5 Inch - 60x Longer Wheel Life

Have used this on sheet metal projects. Excellent and fast cutting. Bought this on a tip from Brandon Lund.

So far I have no issues with this product, I have cut off stainless steel bolts and sheet stainless steel and angle iron,, and I have even cut fiberglass with it, if you respect the tool you will not have an issue with it either,,

el disco corta muy bien, los discos están hechos para espesores pequeños pero corté fácilmente un eje de transmisión de 1 1/4, veremos cuanto dura los discos :D

I havent had time to use it yet. It is well made.

cuts expanded metal like going thru butter

Havent used these enough yet to give a complete review, but they do cut steel OK. The diamonds are embedded well enough that they dont fall off. My only advice is to cut straight through and avoid rubbing the steel part of the blade on the metal being cut. Heat might become an issue. if steel gets too hot it will warp. So far that has not been an issue.

I finally got a chance to use the cutter.so far I’m very impressed, less spark and dust. It seems to cut clean and fast.
