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

Pretty good! The handles are screwed on, so make sure you give them a snug before using. Easy to build into a guide or tool for auto dressing your wheel. I have a Delta wet grinder, and these guys did a great job of flattening the wheel after I let someone else sharpen a bunch of lawnmower blades...they managed to both groove and ovalize the stone! Good value, methinks.

Works great

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.

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.

I bought a sharpening tool that has a 10” wheel that runs in a water bath. It was a good 1/4” out of round when I “won” it at a local auction. I bought these and used the coarse one to do the majority of the work I clamped it down to the tool rest and turned the wheel by hand. I moved the tool closer many times and eventually switched to the fine dressing tool. For this job they worked great. They still have enough cutting ability that I saved them for use on my electric grinders.These were perfect for the job I purchased them for and I’m quite sure that I will use them when my electric grinders need the wheels dressed.I would recommend these.

This set of two dressing tools make indispensable companions to any bench grinder. The units are substantial and reasonably hefty, with a good solid feel. Using the coarse (36 grit) instrument, I was able to bring my 8 inch grinding wheel (which had not been dressed in over 15 years of use) back to an clean, even surface within 30 seconds of application. I followed with the fine (120 grit) instrument, and brought the wheel to a much smoother surface, again within 30 seconds. After restoring/dressing the grinding wheel, the tool surfaces showed only slight wear, indicating a good amount of residual for future use. I have nothing negative to say at all, I would buy this set again.

Works well small in size

These are very nice!!
