Questions about this item

Will the 5/8-11 thread on the 804-12306 fit the grinder I already own?

The 5/8-11 thread is the standard spindle size for most 4-inch angle grinders, so it will mount directly onto any grinder with that same thread.

How can I confirm the brush is running at the rated 9000 rpm after I install it?

Check the name-plate on your grinder; if it shows a no-load speed of 9000 rpm or lower, the brush will operate within its rated limit.
