Review on 🔪 High-Quality Norton Grinding Wheel: Premium Bench & Pedestal Aluminum Oxide Wheel, Very Fine Grit - 6 Inch, Pack of 1 by Brian Kumar

Second try. The first wheel was not round and had an unsteady lateral runout. The second try was frankly awful with the included hub, which was loose enough for a large rat to fit between the hub and the wheel. The hole in the center of the wheel was not round, about 0.996 x 1.006 inches. The wheel width was about 0.97 inches. Made a matching socket; The wheel was then 27k transverse, about 15k radial with lapped shims. It could have been balanced, but it wasn't good out of the box. The hit on my grinder shaft is 1 thousand so it's much worse and very noticeable. The bushings were disposable. The bushing set with the first wheel was better, the wheel was worse.
