SALI 10 Pack 4-1/2 Inch Grinding Wheels for General Purpose Metal & Stainless Steel, Aluminum Oxide Grinding Disc for Angle Grinder, Depressed Center 4.5" * 1/4" * 7/8"(115 * 6.0 * 22.2 mm)

The disks for the money grind well and are durable.

The workers are happy with these reasonably priced grinding wheels. We have purchased them several times.

Seem to be well-made. Better deal than even HarborFreight.

These are good grinding wheels! Sure, not top notch, but great value! I will buy again.

These are some of the cheapest that you can possibly find and they last longer than the expensive ones that you can buy in Home Depot or other hardware stores

Was a little hesitant when I saw all the 5 star reviews from our Vine voices, stating how "quick" they ground, taking minutes to grind down a bolt??? After using these to fabricate some frame braces on a truck, they work like a charm, and on the cheap also. Ground down 3/16 and 1/4 steel like a hot knife thru butter. Was using a metabo 11 amp grinder. No noticable wear after grinding down 3 braces to fit, and I mean I looked for the wear. No wobble either. Worked as good as the dewalt, maybe even better. Will definitely buy more when needed, but the way the first one is going, may be a while.

Best grinding disk ever used

What i have learned from grinding discs js they either last long but grind off material slow or grind fast and run out fast. These run out faster than say a Dewalt grind disc but are so much cheaper and help finish projects faster. I believe these are the best bang for your buck.
