Case Trimmers

[JackEllis]

I have a Lee Power Trimmer. It trims the cases to length well enough but it falls short in the deburring and chamfering departments. That might be a matter of too much pressure on the drill when I'm cutting.

I looked at one Youtube video for the Forester trimmer and that fellow still had to do some cleaning up on each case. So the questions are, a) how well do the Giraud, RCBS, Lyman and Forester case trimmers chamfer and debur; is there a solution that will work with a drill press or a small bench lathe.

The Giraud trimmer is the best. I've owned the Gracey and it produces perfect cases too. The knock on the Gracey is that it is under powered. I didn't find that but was only trimming 223.

I currently use the Giraud Tri-way and it does an excellent job. I didn't want to wait for Doug's bench trimmer and figured I could upgrade later. I've seen where people mount it to a fixed motor like a bench grinder. Depending on the speed of your lathe, it would work too. I use a corded drill.

I was hoping to find out whether any further cleanup is needed with whatever trimmer you use. Mesa, can I assume the Giraud trimmers also chamfer and deburr without any additional work, 'cause that's what I'm after.

I've always used the inexpensive Lee trimmer setups, the kind you put in a drill chuck. No complaints. And I use the Lee Chamfering/deburring tool, as a step 2 to the trim process.

I also have a Hornady tool similar to this. More aggressive cutter than the Lee and requires a softer touch.

Forster makes a 3 way attachment cutter. It trims, chamfers and deburs. It is caliber specific.

I love it. I highly reccomend it

Forster also makes a trimmer for a drill press

RCBS makes 3 way cutters for their trimmers.
Saves me alot of time.
223, 308, and 6.5 creedmoor.

But I made my own drill adapter and use a drill.

I cannot compare to other setup, as the Giraud is my first and hopefully last brass trimmer. The Giraud power trimmer chamfers and deburrs nicely (I have 3 different cutter head/case holder setups (.308, 6.5CM and .223). It took me some trial and error, but once I got the cutter in the correct orientation, the cuts were perfect and consistent. I would highly recommend it.

Thank for all the replies. I did a little research and determined that part of my problem might be drill speed (too fast) and part might be pressure (too much).

I may still get something else but for the moment I'm going to order new cutters and see if they work better. Chamfering and deburring by hand takes more patience than I can muster, even if I only do it once or twice a year.

For those of you who use a lathe with the Forster, RCBS and Giraud trimmers, what speed do you run at. The small benchtop lathe I have runs at better than 3,000 RPM which is probably too fast. I also have a variable speed drill press and an old 12V drill I could repurpose.

I have the RCBS powered trimmer with the three way cutter. It works very well. It's very fast and easy to use. Loading/unloading the cases is simple. I haven't timed it but I'd guess it runs around 60 RPM.

A big plus one for Giraud. I have had one for several years. Cutters and shell holders for .204 Ruger, 223, 300 Black Out, 308 and 6.5 Grendel. Takes me just a couple of minutes to change calibers. Only real problem is fingers get sore after awhile!

Here's an adapter for a drill for the forster if you decide to go that route

The Gracey trimmer with a 3000rpm motor and a carbide cutter work great!
