POWERTEC Bench Grinder Wheel 8 Inch 36 Grit, Aluminum Oxide Grinding Wheel for Bench Pedestal Grinder, 1" Thick 5/8" Arbor, Sharpening & Shaping Drill Bits, Blade, and Chisel 1PK (15516)

I reluctantly purchased this tool because I really didn't think it would 1) work well and 2) last long. Well, I was wrong on both counts. Have 2 bench grinders, with three stone wheels between them. Working with aluminum on grinders is a mess, because lots of aluminum gets embedded in the wheel and doesn't come off even when hit with steel bar. To add to the aluminum mess, all three wheels (fine, medium and coarse) were worn unevenly. Round corners, groves in centers, etc. This little tool cleaned up and trued up all three wheels in a few minutes. Add to that the tool has enough life left to do all three wheels two or three times again. The trick to using this tool compared to the "pizza cutter" tools, is to not push hard. A nice light touch does the job. The wheel just wears down in a flash. There was stone dust all over the work bench after using this tool. I did push hard at one point using the edge of the tool, and the diamond grit wore off in about a 1/8 inch wide stripe half way down the face of the tool. Pushing hard got me nowhere. Light, easy pressure works best. Now the wheels are square. And 95% of the embedded aluminum is gone. Ground an old screwdriver square and true with the wheels and everything was smooth sailing. No grabbing, no bumping, just smooth grinding action. For half the price of a new wheel, this tool did a great job. Saved me buying new wheels all around. Nice tool. Great bang for the buck.

My bench grinder had an uneven spot on the wheel and gave me problems sharpening my tools. This worked like a charm but be aware, you're gonna get grinder shavings everywhere.

Used it on 2 different wheels, 1 of which was pretty bad. It works, nothing broke or wore off the item itself. It did it's job.

Very useful tool for dressing your grinding wheels. It cuts quickly so varying pressure depending on the hardness of your wheel ls advised. The design is great in that it allows you to dress your edges by varying degress simply by moving the tool to apply whatever radius to tthe edges.

Many complain about it wearing out as soon as they use it, but I think they are pushing WAY too hard. If you gently apply it to the stone, it works excellent. do NOT ram it into the stone, apply it gently, and it WILL level the stone just fine... Makes my stones super flat and dressed.

My new grinder wheels were out of true and this brought them in. Much less vibration.

Nice 8 inch grinding wheel.. welll balanced.

It’s what it is supposed to be. It worked at dressing (flattening) my grinder wheel. Do I think it will last more than a handful of times? Probably not. I’m not sure this is really better than using any of ten random scrap things I could likely find in my garage. For a few bucks it’s fine.
