Looking to buy some but which ones? I'm planning to take off the sharp edges around the ports.

These are very good for the money.

It might be worth using demel type small sanding drums , you will be less likely to take to much off or slip and cause damage if this is your first attempt at this, if you planning on taking quite a bit off then the burr cutters will be better.

How about a file? A small half round file should sort it

I use them with an air grinder. If you're careful they can be used on the casing transfers and are particularly good on cast iron barrels,you just need a steady hand. The dremel can be used to finish off and polishing up.

That's all I use to chamfer the ports, you can just about get to all of them if you're careful.

Things go wrong much more slowly with a file!

Amen to that.

What a brilliant saying.

"Things go wrong much more slowly with a file!"

Love it. So true.

I tried one of those 3 legged glaze busters in a hand held electric drill once. Just a practice run on an old knackered barrel, now that did quickly get out of hand, it caught the sleeve of my sweatshirt and got jammed. I had visions of it ripping a chunk out of my arm, but thankfully it jammed in the material when it wrenched the drill out of my hands. I leave that job to an expert these days and binned the glaze buster.
