I recently added a pair of 8" pedestal grinders. On the first one I have a braided wire wheel and a coarse Norton (Gemini) general purpose coarse wheel. Was lead to beleive it was US made but is in fact made in China. Seems to work well. I use it for general grinding.

On the other grinder I have a 60 grit white alum oxide, J hardness, Norton wheel (was $40 from MSC) that I use stricly for grinding HSS. It works well. On the other side I have a brown norton wheel that came with the grinder, the wheel is probably 20 yrs old, it is med grit. I think it is a surface grinding wheel actually. I use that for general grinding when my coarse wheel is too coarse for the task.

These are older Brown & Brockmeyer 3-phase grinders. They are controlled by the same VFD that controls my mill. I keep all the machines switched off and only turn on the one I wish to run at any given time, and control it from a For-off-rev switch w/ a speed pot. I wouldn't recomend 3 phase grinders but they work, one grinder was free, the other was $20. The price was right and they were on pedestals.

Sell your cheap import bench grinder. Getting these B&B grinders setup made grinding HSS tool bits much easier.

Finding grinding wheel info is very difficult. I put a lot of effort into research before I bought my wheels, good info is hard to come by. Use the search function here, and there are some things on the
