    I am making a tool grinder setup. I want to use the 1.25" hole 6" wheels with the standard 4 bolt pattern. I have looked pretty hard and cannot find the radius of the bolt pattern. Anyone know?

    Get a wheel Bruce

    Even a junk wheel

    I am not in the shop, but I think it is 3 1/4

    An old wheel may disprove me though [img]smile.gif[/img]

    What Mr. Oder said, or contact a place like Norton Abrasives. They often have a print they can provide of their grinding wheels that they can zap to you or fax.

    I went out to the shop and measured a new Isreal made wheel.

    Bolt circle dia.-3.265"

    Bolt hole dia.-.395"

    It's been my experience the holes don't always line up and I have to drill out the holes to get the bolts in.

    There, it is in inches, not metric or anything else.

    I have a wheel, but I also find that the dimensions don't make sense or fit other grinders I already have. I wanted the one I make to be right on the money - so as to minimize the differences between my standard wheel and the variable results I see on my e-bay purchases.

    Bruce, the dimentions I gave in the post above are taken off a new wheel. I guess the best way to do it is to measure several different brands of wheels. It would be a good idea to measure several brands of grinders where the wheel mounts to it. I was kind of hoping that some others would measure a different brand of wheel for you and that is why I listed the brand I measured.
