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)

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 have used others and these last much longer and does great cuts.

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.

Cheap

Get the job done

I took these out to the shop to give them a try and they worked as expected. I made four cut offs on an 1/8 X 2 steel bar and they performed as expected and I didnt experience any issues. I am not sure what it means in the title of the disks that refers to Professional for Stainless Steel, Angle Grinder Cutting Wheel. Does that mean they will cut stainless steel or that they have stainless steel in them. I am thinking it means they will cut stainless steel. At 38 cents apiece they are a good buy and a whole lot cheaper than big box stores charge. I expect these will last me the rest of my life (I am an old guy so that may not be saying all that much).

Good

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
