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)

I tend to use my grinder quite a bit, and having extra cutting wheels is a necessity. These wheels seem very sturdy and cut through metal or other objects quite easily. Having a large number of them allows me to go to a job knowing that I will have enough to complete any amount of cutting that I may have. I would definitely recommend them for the way they perform.

Cheap

Good value for the money. I havent noticed the difference between higher price cutting wheels and these.

The first thing to say is that this cutting wheels is packed in a plastic box, so it looks neat and easy to carry. Secondly, each can be used about 30 times, which should be considered normal. Anyway, it did what I needed for the job, and Im happy with it.

Get the job done

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.

As the headline says, after using several of these to cut various metals around the shop for a few days, number one they seem to wear down a LOT slower than the generic ones from the Big Box stores, but most importantly they cut well and dont have a tendency to Grenade ... Add in the cost (being about half of the Big Box styles) and these are a definite winner for the home shop, Garage, etc. As with all cutoff wheels, if using on thicker metal, keep them cool (meaning take a break here and there during long or deep cuts) and these are definitely a great alternative to the cheap throwaway styles most places carry.

I was concerned about these cutting through oilfield drill pipe - really thick stuff - see picture. As you can see, they cut beautifully - nice, clean cut. Building a pole barn. They must be tougher than normal wheels because they seem to last longer. Very happy with these. Best I have ever worked with. Sure beats using a cutting torch!

Good cutting discs... very comparable to anything I have previously used and purchased locally. Had a chance to try them today and they cut well with very little wear. They are a good price point and cheaper than Harbor Freight. (HF wants $6 for 10.) They are as described and pictured on Amazon - 5 Stars from me

Fits standard angle grinder well, cuts well. Disc are very thin for precision tight cuts, but, will also break easier than thicker discs. Good value for the money, nice compact storage case.
