I'm setting up a dedicated grinder bench with different wheels on different grinders. I picked up a pair of scotchbrite wheels in two different grits and they will be part of that.

Here is the 3M technical web page about their family of deburring wheels:
https://multimedia.3m.com/mws/media/629 ... wheels.pdf
I learned to use these while working at a precision machine shop. Got hooked, too.
There are other manufacturers of these wheels, too.

I primarily use 1" wide x 6" diameter convolute wheels, fine grit. Sometimes a 1/2" wide wheel works better for some parts.
They are basically abrasive powders captured in a soft media (different hardnesses are available) that wears away exposing fresh abrasives.
The result is a grey powder against my white shop wall! And beautifully deburred parts.
The more you contact the parts against the wheel, the more material is removed. It is not an aggressive process for most metals. Heat is generated.
It also can remove the hard shell from hot-rolled steels, without much removal of the base material. It just gets polished.
For usage calibration, I consumed 2 wheels while constructing my Mikado.

I even use it to deburr sheared sheet metal edges, which are otherwise quite dangerous to handle. For me, anyway.
Just make sure you are using a trailing contact, or else the thin parts will catch the wheel and disappear into the Shop Ether.

Thanks Russ, will study the guide. Sounds I "need" one or two.

Here's a pic of the deburring wheel setup I made 30+ years ago.
It still works as designed and gets used nearly daily.
