Can someone recommend an inside/outside chamfer tool?

I'm mass prepping 223 and trim/in/out chamfer with an RCBS 3-Way Cutter but the cases that I dont need to trim I use the Lyman bits which is 2 separate steps. Is there a good in/out chamfer tool in 1 that can be drill mounted?

Cheers
 
My favorite for inside the neck is a 1/4 inch shank carbide burr, but I have never found anything very good for the outside of the necks, although I do have a unique design concept that I might produce some day.

I use a the RCBS 3-way cutter for 223 (and 308 as well).
Sorry if I sound dense, but I can't understand the what the issue is.

I am of the thinking that if a case doesn't need to trimmed, then it doesn't need to be chamfered either.

Put differently, if you're processing at batch of brass, and say a handful of them didn't "grow" past your trim length after you re-sized them, then re-chamfering them would be a redundant step (as they would still have their original chamfer)..... at least that how I would look it.

Stainless steel tumbling can peen the case mouths so chamfering cleans that up a bit. This is bulk plinking ammo so like you and others have said its probably not even necessary.
 
I used chuck brass in drill and use the finger tip ones, hundreds of sized and trimmed .223 chucked in drill. When you can afford it, get the Frankford Arsenal Platinum Series Case Prep and Trim System (or similar model), .223 and .308 is so much more enjoyable now. I now re-size all brass, then trim all brass with built in adjustable trimmer setting, last step (all at once), inner/outer chamfer, flip over and clean primer pocket..so much easier...so much.

Wish.com has an excellent outside turning tool for $5 plus shipping. It's made to chuck up into a drill or drill press. It's much easier to hold onto the brass with your fingers and just keep running them under the drill press, while it's running.

The finger types usually have a 3/32 pin protruding about one cm from the center of the rear (outside cutters). Use that pin to chuck it up in a hand drill or drill press and you can clean up a lot of case mouths pdq.

Would this peening occur if tumbling was done without the SS pins?
 
Why do so many guys dump on stainless media over minor case mouth damage?

I mean seriously... Nobody ever thought maybe you should chamfer the case mouth after you tumble?
 
I have a Giraud that takes a lot of effort out of the trim and deburr process, but it requires a special shell holder from Giraud or a gunsmith made one. I use a Wilson deburring tool when I trim with a manual trimmer for the cartridges that I don't have a Giraud shell holder for. There are times that I chamfer when I haven't trimmed. New brass when its not trimmed accepts the bullet easier if it lightly chamfered. Once fired brass from factory ammo that's still too short to trim gets lightly chamfered for the same reason. Winchester factory ammo uses an ugly crimp, and when possible I trim that brass below the crimp, even though it results in a short neck.
