Grinding Wheel Dresser

Meets Expectations

Worked perfectly fine on my grind wheel, didn't seem to wear down the tool at all. It will be a bit before I need to redress my wheel but I will update when I do

I bought this at the same time I purchased a 8 inch low speed grinder also from Powertec. This did a great job of truing the wheels in about a minute. I would have given it a 5 star rating but the diamond surface was uneven with a heavier build up just off center that I had to compensate for when using it. It still does a fantastic job despite this however so I will continue to use it until I wear it out. I also have one of the old fashioned "death wheel" style grinding wheel dressers that I got from the hardware store for twice the cost but I don't know that I will continue to use the older one given how well this Powertec dresser performs. I should also mention that it makes far less dust than other styles of wheel dresser make and still does a better job.

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.

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 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.

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.

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.
