4 1/2-Inch Cut Off Wheels, Aggressive Cutting Discs for Angle Grinder, Metal & Stainless Steel, Pack of 50

Great cutting ability. Lasts longer than most

Norton are good discs. They work good at a reasonable price.

These are brand name that work. Some other are not good. I had one brand blow up. Not safe to use. This one works well and safer.

Needed to cut off an old lock missing a key. I mounted this on my angle grinder and proceeded to the “big” job. It cut through the lock like it was rotten wood. Literally under a minute and the lock fell off. Thank you Norton and Amazon.

These are some of the best cutoff wheels I've ever had the pleasure of burning through. they seem to last at least 5x longer than the horrible fate brand wheels... and despite the price I'd argue they are worth every penny. Mostly work mild steel myself so your results may vary.

I needed a fine edge cutting disc for cutting aluminum tubes for deck rails. This was a pack of 5 disc. I used one disc to cut off the ends of 16 rails and thought it would take off at least 1/2 inch of the disc. It gave a smooth clean cut and there was at most 1/4 inch of the disc used.

Use this for a fence project on an battery powered grinder. It is a quality, strong abrasive wheel that does not easily dull or break. Highly recommended purchase.

Good for the price but they do run out of material very quickly. *Used to cut 2 inch steel exhaust pipe*
