What methods/tools are you all using for this process these days?

Any reason I can't just chuck up a tool like this in my lathe and run a bunch of cases that way? Drawbacks/benefits to this technique vs. others?

That'll do it. If you had a way to spin two of them you could speed the process by only handling each case once for both operations.

I gather the RCBS Trim Mate works well for this too.

I use the Lee hand tool...needless to say, trimming, chamfering and deburring 20 5.56mm military brass is enough for me at one sitting. It will take me quite a while to get all my mil brass I got ready to shoot.

That should work well, Wayne. Be sure to not use a high RPM on the lathe.

The only drawback I can see over using an all-in-one setup like the Trim Mate (I use one - it's very efficient), is you have to change tools a couple of times. With the Trim Mate, I can chamfer, deburr, and clean the primer pockets on the same case in a couple of seconds - no tool changing, and no need to handle the same case three separate times.

I use the Lee trimmer chucked up in a drill. After the trim, I just use the RCBS chamfer tool as the brass is still in the Lee trimmer. Two pulls of the trigger on the drill to do the inside and out. As I'm watching TV.

I'll ask for a Trim Mate for next Christmas. :)

Also uniform the primer pockets and dedur the flash hole alomg with the above. You can change what tool heads are on the trim mate.

Something I do is to use a 3-way cutter on a RCBS trim pro power trimmer but I didn't like the debur on it so I use it as a 2-way cutter and replaced the debur pilot with a standard pilot. A 3-way cutter can use standard pilots or if you like the debur on it just buy new cal.spec debur pilots this leaves a station open on my trim mate five stations 1. calibur specific wire brush for cleaning necks, 2. Flash hole dedur tool, 3. Primer pocket uniformer or primer pocket brush, 4. chamfering head (not used much) and 5. aVLD debur tool (this is why I took the 3-way cutter and turned it into a 2-way cutter I like the VLD much better.
It took me a while to get set-up like this but I did do it the way you are now. I would just keep my debur chamfer in my pocket had a couple bowls full of brass sitting around places you tend to spend more time in the TV room in the shop sit down to watch TV debur 20-100 rounds depends on how raw my fingers already where.

That's a good point about having to change out the tools. Admitidly, this aspect of case prep is not the most exciting and I generally like to do a bunch and get it over with.

Is this the one:

Do all four of those tools in the lower section rotate at the same time when the machine is on? The upper two brushes are in storage?

I prepped 2,000 .223 cases over a couple of days recently.
I used a big flat container to pick them out of, and a gallon coffee can to throw the finished ones in. Set both containers on a high bench stool right under the lathe and go for it!

You can chamfer them as fast as you can pick up a handful, do it, and throw them in the can.

When you get them all done, flip the cutter around in the chuck and go through them all again to de-burr.

I have the RCBS 3-way cutters for my .30/06 and .223 brass.

I use the Lee trimmer chucked up in a cordless drill. After the trim I use the Lee chamfering and deburring tool I have about $10 bucks in the Lee Tools for that setup,I only load about a 100 Rds. at a time so it works great for me.

The rectangular indentation on top is a place to pour a little mica or other dry lube to dip the brushes in every now and then. Some use it to store tools not in use, but the lube for brushes is the intended use.

I use the Lee trimmer. I put the lockstud in a battery drill. I put the case in the lockstud and can trim, chamfer and debur in 5 seconds or less. The complete Lee trimmer cost around $10.

Same setup here with the Lee and battery drill or a low-speed, high-torque electric drill for large batches. RCBS chamfer tool to clean 'em up. Cheap, fast, consistent, and efficient. What more could you ask for. I do prefer the cutter with the wood shifter ball.
