3 Pieces Grinding Wheel Dresser Diamond Grinding Wheel Stone Dresser Tool with Flat Diamond Coated Surface for Truing Deburring Wheels

Worked great! They cleaned up my bench grinder wheel after I clogged it while grinding some aluminum and copper. It also flattened out the wheel so that sharpening drill bits is easier now.

A little small but they work well.

As others have posted these are a bit flimsy and one of them was loose from the factory. Tightening it up was no problem for me. YMMV. They work okay and squared up a wheel on my 8" bench grinder as well as the star type wheel dresser I also have. The dressing surface doesn't appear to be very thick, so longevity may be an issue. But time will tell. Not bad. I'll give them 4 stars.

I was skeptical at first because of the price. Many complained about the loose handles. I know how to tighten a handle. The tool worked very good and very fast. Some noticeable grind medium loss but surely good for another ten times. Price was really good for this. Needed the shop-vac ready to catch all the rock turned off the grinder wheel.

They done an OK job of trueing up the wheels on my grinder, but are vey flimsy, and from what I can see they will only be good for one more truing. The handles will not stay tight, and one of them came in the packaging with the handle and bolt completely off. Made in china junk, like most everything else nowadays.

Works well on a bench top grinder for a low price. Use a gentle touch and don't forget to readjust the tool rest after trimming the wheel.

Used on stone and scotch brite wheels on a grinder and worked fine on both wheels. Fast and efficient. Blew the dust and debris from the diamonds and looks like brand new after 4 uses on stone wheels and 4 uses on scotch brite polishing wheels.

The order showed up later than advertised, but not terribly so. Package was in good condition, no damage to the box inside. When I opened the box, a couple of parts fell out, as one had jiggled around enough to completely unscrew itself! Both of the other two were loose and about to fall apart as well. After tightening them up by jamming a flathead in the tube, twice, they do ok. I'm going to take them apart, replace the missing washer from the jumble, and loc-tite them. Well, the two metal handles at least. The black one is plastic. I may try to make a new handle myself, but not soon. The manufacturer should use square nuts that just barely fit inside the square tube, and maybe include a surface on the handle to put a small wrench on? Hex, square, two flats, etc near the handles end.
