Hotop 6 Pieces Thick Reducing Bushing Adapters for Bench Grinding/Sanding Wheels - Id 1/2 inch, Od 5/8 inch, 3/4-1 inch - Steel Reducer Review

Good tolerances and fit. Reasonable price for 2 sets. Better than the hub I was able to machine out of HDPE for a diamond blade on my angle grinder. I recommend.

Brand new Baldor bumpers and they won't fit the 3/4” shaft. Why not? Well, their inner diameter is off. I could try turning them on my lathe, but I could just return them. The rest of the finish is pretty nice.

In support of ShawnB's review, the 3/4" ID socket is slightly under .750 and needs a slight honing to fit the older Baldor 3/4hp (model 332) buffer to fit. Otherwise good quality, good product.

Brand new Baldor buffer that will not fit a 3/4” shank. Why not? Well, their inner diameter is off. I could try turning them on my lathe, but I could just return them. The rest of the finish is pretty nice.

In support of ShawnB's review, the bore of the 3/4" socket is slightly under .750 and to match the older 3/4 HP Baldor buffer (Model 332) had to be improved a little. Otherwise a good quality good product.

I bought this to install a 1" ID Scotch-Brite polishing pad on my old Bronco 1/2" grinder. It worked flawlessly and kept the wheel in good condition and true. It should be noted that this will not help you balance or adjust your wheels, it will only reduce the risk of the wheel falling apart because it is too far off center on the axle. .
