    Wobbly Wheels?
    If you find that your wheel isn't running true, it is likely due to your grinder's wheel washers. We highly recommend purchasing Raptor Grinding Wheel Washers to fix the problem.

    Grinding non-heat treated steel such as carbon steel, aluminum and other soft metals will cause irreparable damage to the wheel and is not covered under warranty.

Great wheel

Comments On Feb 09, 2020:I am very happy with this wheel . It was tough not to burn the HSS tools with the standard wheels. I like that there are basically no sparks. This is especially important in an area with a lot of fine wood shavings and dust. The wheel grinds very fast even at 350 grit. You can still blue the tools if you are not careful. You do not need any pressure on the tool. The tools are very sharp and provide a clean cut.

I am impressed

Comments On Feb 01, 2019:I had a single steel 180 grit CBN wheel on my Rikon 8"grinder. It would take it a while to spin up to speed and it did great.
After watching the video on this, I decided to buy the recommended pair and got them today. I quickly installed them and gave them a try. I am impressed. The grinder is very quiet and comes up to speed rapidly. they cut fast and they cut great. The 350 grit leaves a very smooth facet and really nice edge.
I recommend getting the pair for your grinder.
