POWERTEC Bench Grinder Wheel 8 Inch 60 Grit, Aluminum Oxide Grinding Wheel for Bench Pedestal Grinder, 1" Thick 5/8" Arbor, Sharpening & Shaping Drill Bits, Blade, and Chisel 1PK (15517)

I've only brought one of these wheels and it was extremely straight. None of those stupid plastic bushings in the middle, it's all stone. Good so far. I bought 60 grit to sharpen lawn mower blades on a daily basis. It puts a pretty sharp blade on, but it's easy to burn the metal and the stone maybe wearing away quickly. I've only used it for a week. Next time I may go to the course wheel which is I think 36 grit. Overall, I like the brand, the price, and especially the straight wheel with no bushings. Even the selection of grit is pretty cool, but I may have got it wrong.

Removed the old wheel and cleaned up the arbor with emory. Used a dial indicator and measured 0.002" runout on the shaft. Installed Powertec 8" #60 grit wheel with 5/8" center hole. Rotated slowly by hand and saw no obvious runout. Powered up, no unusual vibration, and touched lightly with diamond dresser. Wrapped wheel with a single layer of smooth tape (to protect indicator) and clamped indicator to tool rest. Measured 0.004" over the 360 degree perimeter. Very good and close enough for anything a human hand can do with a bench grinder. Made a few test grinds against some scrap steel angle. Wheel performs exactly as it should.

Was looking for something to cut steel copper and aluminum. Unfortunately this may be the wrong grit but it either loaded up on the soft metals or developed a shiny surface with steel and would not cut. I haven’t used a cutoff saw in years so this wasn’t expected. I moved over to a diamond grit blade and it did the job.

Working great

I bought a 2 pack previously but I dropped one and it broke into pieces. Works great.

Guess you get what you pay for... the 100 grit wheel is out of round and wobbles on my grinder. It will serve the purpose but make sure you too can accept wobble from your grinding wheel

Balance of wheel. Smooth and takes forever to stop after shutting off grinder. 👍👍

At first, I thought this was terrific as I started up my grinder and it was perfectly balanced, or as close as can be. However, the first time of using it, it went out of balance and absolutely defies dressing it back into balanced usefulness. It vibrates anything on my bench right off and throws off a great deal of grit in use. It'll wear out really fast, though, so at least I won't have to suffer with it too long, lol.
