ATLIN Grinding Wheel Dressing Tool - 36 Grit & 120 Grit Diamond Dresser - True Up and Restore Grinding Wheels

The tool is fine and performs as expected, but the really nice point is I DID NOT PAY FOR OVERNIGHT SHIPPING, but about mid-afternoon the day after I placed the order a very nice Amazon driver wallked up to my door with the package. That's impressive!

Works good! Easy to use

I like the coarse dresser, it wacked my old really mis-shaped 8" gray stones right back into ship shape shape. As you can see that took quite a bit off of the diamonds. I'm guessing I'll get maybe 10 uses out of it. In the pics the central areas in the grains are worn flats. This was quite a fast wear rate compared to some (expensive) diamond dressers I've used. I'm not sure if the fine dresser is useful. I tried it on another wheel and it worked, but nothing like the coarse one. Overall I'm happy with this purchase.

I've been trying to use my big, heavy and bulky old fashioned style wheel dresser that has the spinning metal wheels on the end for years and it never quite seemed to leave the grinding wheels nice and cleanly dressed. But these worked like a dream! The way I always thought a wheel dresser should work! Left a nice clean and smooth surface. Best part is they're nice and light and compact! I would suggest using a dust mask when using them though. I could see some very fine dust particles being blown through the air. The only thing I'm not 100% sure about is the "Longevity" in the star ratings above as I've only used them once on two different wheels so far. But went out on a limb and gave it 5 stars as they are diamond so I expect they'll last the rest of my lifetime anyway! Not something that gets used that often in my humble shop. Didn't see any kind of wear at all after their first trial run.

SUPURB! I’ve never had a two piece wheel dressing unit, it works great! Have two different grits made for a superb finish on my grinding wheels, very flat, even finishes

The corse to worked great, still can do more wheels, I did 3 first time. However the fine tool lost its finishing media on the first wheel

TRUES THE STONE VERY WELL USE LIGHT PRESSURE FOR TOOL LIFE

These grinding wheel dressers work quite well (set up a shop vac to collect the dust that the wheel will throw off when using them though!). They did the job quickly and showed little wear after dressing three wheels. The one slight drawback is that their surfaces aren't dead-flat, so if you just press them against the wheel and hold them stationary, you'll get grooves or an uneven profile. It's not major, but enough that I wanted to avoid it. I found I had to move them back and forth manually, while sighting down so I could see the profile of the wheel clearly. It was easy for one side of the wheel or the other to end up slightly rounded, which was a little strange since I never positioned the dresser in a way that would have rounded the corners. I was just working freehand, but by watching the profile of the wheel as I moved the dressers back and forth, I managed to end up with nice smooth, square profiles. Using these was slightly fiddly, but they ultimately worked very well for what I needed.
