Mudder 3 Pieces Grinding Wheel Dresser Tool Diamond Stone Grinding Dresser Tool with Flat Diamond Surface for Restore Bench Grinder Truing Deburring Smooth Surface

I use these consistently I think it's been a year or two they're still good I think they probably will last a very long time, another words I don't think they will ever wear out

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.

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.

A little small but they work well.

The nut to attach the handle to the dressing block must be balanced over the hole inside a 1/2 inch square tube 2" long with the hole in the center. It must somehow be held in place (I found a needlenose plier to be useful) while screwing in the handle. Once it relatively tight, one side of the plier can be used as a wedge to keep the nut from spinning while final tightening is done by turning the handle with a vise grip. Addition of a lock washer (supplied by you) will keep the handle from loosening. Handles should have been attached at the factory.

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.

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.

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.
