Benchmark Abrasives Grinder Cut Off Wheels 4 1/2 Inch Aluminum Oxide Depressed Center Thin Type 27 for Metals, 1/4" Thick 7/8" Arbor, Angle Grinder Cutting Disc, Grinding Cutting Wheel - 15 Pack

I wasn't expecting much with these discs but i will be a returning customer. They perform as well as almost every other grinding wheel i have tried and they hold up surprisingly well. I wasn't too worried about the performance as i was durability and longevity and in both area these performed well. I did have 1 disc that wasn't balanced perfectly and had a good vibration but after 30 seconds of use it was down to tolerable levels.

These definitely hold up well. Cut some 1 inch bolts off with ease. Good quality

Benchmark...lasts longer than other brands

Quality

Awesome value, highly recommend.

Great product---Grinding wheel does an excellent job,lasts much longer than many other grinding wheels I have used. I highly recommend trying them you won't be disappointed... can't beat the price, I also use benchmark flap discs and cut off wheels -high quality as well , excellent company and fast shipping

Not terribly impessed. These discs are hard, which means they wear slow, they also polish and don't remove material very fast. Maybe with an 11amp grinder that you can lean on they might be a little better. If you want a disk that will remove steel and allow you to move on to the next step these are not it. If you want a disk that will last a coons age these are right up your alley.

I've been ordering these for a couple of months now and we are very happy with them. In my opinion these are the best out there for the price. We have tried some of the high end super expensive ones but often they are to hard for some of the softer applications. If you are grinding welds out all day then these are probably not for you. But for a great all purpose grinding disk, give them a shot. You will not be dissapointed.
