The first time I put new grinder wheels on the slow speed 8" grinder, I went with the OneWay wheels, a #80 and a #120. They were very good, no complaints, but this time around, I went with the Norton 3X wheels, this time a #46 and #80. I found that the #120 wheel was not of much use, it loaded up a LOT in use, and I found I did not use it much.
I did use the heck out of the Oneway wheels, they ended up being 6" in diameter, so I certainly did get my money out of them.
The old wheels, just about 6" now.
To show the amount of wheel that has been ground off.
Here is one of the new wheels.
One thing I did notice about these wheels is that I had to move the balancing nuts a lot further off the center to get them balanced, than the Oneway wheels, does that matter
Nice to have new wheels!
