I have use RCBS's 3-way cutter on my powered Trim-Pro, that coupled with their prep center was some of best money my wife ever knowing let me spend... Truth be told, they were her idea, she lets me use them to prep her brass.

After I trim cases, I throw them in the tumbler for about 24hrs. It gets rid of 90% of the flashing. The carbide trimmer I use for the 223 cases leave almost no flashing.

I also have the 3 way trimmer from rcbs for 223. It works pretty well but you have to be very careful of how you set it. It can put a knife edge on the mouth.

At the casting bench in the sky. RIP Bret.
I'm sure this warning will be unneeded for most here, but you can go way, way, WAY overboard in deburring!!! I speak from the experience only an over zealous 22 year old can produce! A bit of 180 grit paper will take care of most out side burrs and things come out smooth as a babies bottom! It is kinda slow though.

Tomme boy, as you noted it is very possible to set up the three-way cutter, so it puts too much of a knife edge on the case mouth. The outside de-burrer gets set to just touch the outside case mouth. And the one that chamfers the inside of the case get set just a little bit more aggressively. All I'm trying to do is break the inner edge and give the bullet an easier start into the case, so the case doesn't shave bullet material not funnel it in. Once properly set the Tri-cut does a nice job and stays consistent. When doing lots of the same brass it saves a fair bit of time.

Your "spaceship", actually L.E. Wilson, tools are easily ruined if you turn them backwards. Like a drill bit, they only cut one way. If you stick it over the neck and grind if back and forth, you just turned the cutting edge over. FWIW

Did not know/never thought about this... Now that you mention it, I started using a Franklin case prep machine recently. As it is automated (vs me manually twisting the cutter back and forth) it does seem to finish the case mouths smoother.

I bought the Tri Cut at a gun show 20-25 years ago, I think it was made locally (Montana) but can't say for sure now. It uses the standard Lyman pilots.

Now I want one too. My #2 trimmer is the same as yours.

I use the Lyman inside and outside debur tools. Don't use them often, just after trimming and I don't do that often. Just after cutting down 223 cases and the Henry needs 308 shortened a tad. Probably need to sell the 500 or so LC 762 brass I'll never get to using.

I'm more of a manual guy... but I recall a guy.. Varmint Al, used what looked like a socket, stuffed with steel wool and powered by a hand drill. This was for deburring outside and inside... a quick press while it's up to speed is all it took.

Thank you for mentioning Varmint Al. I'd forgotten all about him. While I'm unable to digest his really technical stuff, he really helped me to be a more accurate shooter and loader.
Also, back when I didn't have any money, I used his El cheapo mp3 player varmint call design. His suggestion of using domestic cat sounds for coyotes was a big success for me in suburbia. Evidently back then, none of the FoxPro type companies were using kitty sounds and our local coyotes hadn't been educated on the topic.

I bought a Girard, which trims for length, inside and outside at the same time. Best money I ever spent on rifle case prep. My RCBS machine now just has primer pocket brushes and uniforming cutter on it.

CW, I think you got a bad tool, and you were turning it a lot faster than the guy in the rebuttal video.

I got into using the WFT, setting the cutting depth using a drill then chucking it in my lathe for effortless trimming. and like you I use an RCBS powered case prep center to spare my hands.

I retired it and bought a new three prong and it works perfectly!

I prepped just over 200 7Mag cases over the weekend.
