3M Silver Depressed Center Grinding Wheel, 87453, T27, 4.5 in x 1/4 in x 7/8 in, Pack of 10, Deburring Edges, Heavy Stock Removal, Stainless Steel, Mild Steel, Right Angle Grinding

These are very aggressive and will remove a lot of material quickly. They do leave a rougher surface than some other discs but that’s what flap wheels are for. Are they the cheapest? Nope. But they last a long time and remove material very well. Time is money in the field.

These wheels last much longer than Harbor Freight wheels. They don't seem to pickup material as much. If you are doing a bunch of grinding it is worth buying.

Work well for the price

These wheels are great they cut like mad but therefore do take power when you lay into them, also being they cut like that it is not a smooth finish although not to bad if using very light pressure, would rate them almost as good as the cubitronII’s. By far the best wheel for the money as far as I am concerned.

we have used this product before and are very pleased with its performance ! also couldn't get a hold of regular supplier But will definitly reorder when we need to.

i am a welder and use alot of wheels the 3m cubriton line is the best you can buy

These grinding discs are incredible. The speed at which they remove metal is insane. They seem to last a really long time too. Just know, Since they are coarse they don’t leave the smoothest finish.,

Not worth it
