How to bore out the hole in a grinding wheel to enlarge it.

I made this an article in the grinding section.
There is a ton of good information in this thread:

Sorry to resurrect this old post;
Searching for a method of enlarging the arbor hole on deburring wheels that are listed as "nylon fiber wheels". So I'm not intending on enlarging a hole in a vitrified grinding wheel. In my case they are 6" diameter 1" thick, and 10mm arbor hole I want to be 3/4". These wheels could probably explode as well and where the mass may not be the same, that velocity on a 3450RPM motor could be damn dangerous.
So has anyone here modified a low cost deburring wheel?
It's a low cost wheel at $9. Intent to install it on Harbor Freight buffing motor. I want to see if this does a faster job of surface finish over time consuming sewn cloth wheel.

The deburring wheels showed up, they are as soft as 'butter'. Easy to drill out. Bigger issue, one was sold with 10mm hole, but it showed up with 16.5mm hole, bigger then the 5/8" arbor size.
For these nylon wheels an ordinary drill bit can enlarge the hole.
The cheap ones from Amazon, work well, leave a satin finish on Iron, Aluminum, or brass/copper. I had a very rusty axe with flaking scale, the wheel did not want to quickly remove this. But on steel with a corroded surface, it removed that easily.
