I bought a Rikon grinder last year at Woodcraft. I think $89.
Well the stones suck. Way out of round, wobble. The center is not standard 1" ,it's only 7/8 and filled with something rather than using spacers. Using the T bar diamond has not properly dressed them. I picked up a diamond point from Enco. This too did not work, until I made a holder, which limits the travel. Now, this thing is smooth and true. While it still wobbles, and will cause me to buy new stones soon, I can say that the stones are cutting nicely. I might go to the CBN wheels once course and one fine. Since those really run true. -- Jeff |

The center is not standard 1" ,it's only 7/8 and filled with something rather than using spacers. Using the T bar diamond has not properly dressed them. I'm pretty sure all of my grinders are 7/8" shaft. I use Harbor Freight wheels because they are so cheap and they work almost as well as the wheels I used to buy at the welding supply store. For the price a slight sacrifice in life is worth it to me. It's not like they only last 1/2 as long as a good wheel - I'd guess they give at least 80-85% of the life. As far as hardness - they work fine and I grind through a lot of ugly stuff including welds. Never had a problem with wobble at all, and I've gone through boxes and boxes of them over the years. Oh crap - you're talking about a bench grinder. Forget what I said. I'm just not going to delete what I've already written, having put so much great thought into my response. Though I do curerntly have HF wheels on my bench grinder and I have no complaints with it either (as long as nobody does something stupid like grinding aluminum on it...). I only keep one stone wheel on my bench grinder and a wire wheel on the other side. I need another bench grinder - more wheels spinning! -- -Mike- |

Other places want around $200 each. Another advantage to cbn wheels, is that you can remove the guards on your grinder, since steel wheels don't explode. Thus using 1.5" wide wheels instead of 1" wide wheels, The only disadvantage, is that you can't grind any non hardened steel. No bolts, no angle iron, etc. |

Which is realy what I want it for. I use my 1" sander for most mild steel. -- Jeff |

True, their main use is for sharpening High Speed Steel, and powdered metal turning tools. They cut faster and cooler, than stone wheels. And since they never need truing, you can mark the wolverine, or other jigs for different tools and be able to reset to those markings for repeated sharpening. When you true stone wheels a couple of times, it decreases the diameter of the wheel forcing you to change the setting of your jig, so that you don't change the grind angle on your tools. |

I think these wheels are aluminum with cbn applied. |

The web page says this.. " These are highly machined 6061 aluminum wheels that are electroplated with nickel alloy." |

Under CBN Wheel 8-inch, 80 grit, 5/8" arbor on the web page it says As long as the wheels are properly used as intended this should not cause a problem as they are machined from one solid piece of steel. which is what I have, but at least some of the others do say they are 6061 aluminum. |

Mine (D-way original) are solid steel |

Good catch. How much do these things weigh? |

Since those really run true. wobbly wheels will cause bearing failure. If they had HF quality wheels, I'd suspect the bearings to fail early unless changed out. |
