SALI 50 Pack Cut Off Wheel 4 1/2 Inch Cutting Wheels 4-1/2 x 3/64 x 7/8 Professional Cutting Stainless Steel, Angle Grinder Cutting Wheel,Cutting Discs with Aggressive Cutting Upgrade (4.5in, 50)

Good disk took me one blade to square off a piece of 1/4 mild steel 10x23 definitely will be buying more after the price drops a little

Cut end off a k1 kerosene barrel, took 4-5 discs but the only one that gave problems was my mistake, well see if they are still this good in 6 months!! Trust youll hear me if it isnt!!!

I go through a lot of these cutting various pieces of metal (sheet metal, cattle panels, etc.). These perform as well as any others I have used. The rate they wear down is based on the density of the material being cut, But they are inexpensive enough that I’m not hesitant to use them frequently.

I have tried Manny cutting wheels and this one lasts longer and seems to be a straiter cut. I will be buying these again!

I am a mechanic and mixed medium artist. That means I cut a lot of different things. For cutting vehicle components, these are fast and easy. I keep one mounted to my DeWalt next to my hoist all the time. For my art, I cut a lot of mixed metals. Everything from re-rod to stainless and some pig iron. These handle it all. Years ago, I had one blade explode and go through my cheek. Since then I only buy Fiber backed blades. You cant do better than these.

These blades are great value and they come in a great storage container. I could not tell any difference between these and the name brand ones. It fit my cordless Ridgid grinder perfectly. Will purchase this brand again.

Bought the SALI 50 Pack 4 Inch Cutting Wheels. They are only 100mm diameter and not 4-inch. 100mm=3.94 inches so they are about 1/16-inch undersize. More importantly, they are too thin. The actual thickness is 1.0mm, slightly less than the 1/24 inch advertised. They are so thin that they do not tighten in my Makita, a problem which I solve by adding a worn-out second blade to increase the thickness at the arbor. And because they are so thin, they shred too easily if the blade is twisted while being used. The brand I purchased earlier was 1.2mm thick that worked fine. The difference doesnt sound like much but 1.2mm is theoretically 44% stronger in bending compared to 1.0mm.

Even my black hawks need to be balanced when starting a new wheel, so I didnt even check for that, since its automatic when you touch the work. They are slightly thicker at 1.2 mm, but thats what I wanted for cutting sections of T-posts, to hang on my 4x4 fence posts, to tie-on some barbed wire. I cant say enough about the low cost, for such repetitious cutting of many T-post sections. Leaves more money for rising fuel costs!

I used for plastic and metal

Bought these to cut some stainless steel brackets. Was very happy with the nice smooth cuts. It did seem that the steel had to heat up before the cut started to move faster. Did at least thirty minutes of cutting 1/8 stainless steel and used about half of one cutting wheel. Never had a cutting wheel break. Good price for the pack of 50.
