How to avoid carpal tunnel when chamfer/deburring?

[NoName47]

Thanks, but $180 will buy me a lot of ibuprofen. None of my presses are even worth $180.

I found mine on sale for 129.99 dont remember where but it was only 2 years ago

Does that Lee chamfer/deburring tool even last couple thousands trimming? I did not buy one thinking it won't last.

My definition is that the bullet is perfectly seated flush with the case mouth - what more do you expect than that?

Well I don't see how that's possible with case OALs varying from 1.155" to 1.137" but maybe it's just me.

I guess we'll see. It's fine after a few hundred anyway...

For the price compared to competitors you could buy two or three and still come out ahead.

I broke down awhile back and bought (on sale) one of these (for years I have used one of my drill motors).

With a pair of both chamfer and debur heads on-hand I can prep 2 cases at a time and get everything done in less than half the time of my old routine.

I can't imagine I can make my own with the tools I have, but what's your sleeve look like?

It looks similar to this tool, but I made mine over 30 years ago out of aluminum, and it's still going strong.

I have one of these

https://www.midwayusa.com/product/1012832133/lee-chamfer-and-deburring-tool

And a couple thousand trimmed .38 Special brass. Not having a good time so far. Ideas?

Don't trim 38spl for starters, but you already ruled that out. By the way, It does suck using these Lee tools on thousands of rounds, that I why the next time I need to do a big trim of 223, I am buying something better. Likely that Giraud 3 way trimmer for the cordless drill.

I don't have a lathe or drill press. What I need is a power drill with chuck jaws wide enough to hold the tool.

A countersinking bit will do a great job of champering the cases. Also can be used to remove the primer crimp.

Plus a 15-year-old granddaughter that needs money for makeup. And yes, I laugh at child labor laws.

Now that's the real solution!

For the OP; Franklin Arsenal trimmer for everything. RCBS case prep or another for just chamfer, deburr.

 

[thomas15]

Cut to the chase and get a decent model I have the RCBS trim mate others are good but once you get one and use it the cost will fade from memory.

I'll second the Hornady case prep trio. I trim all my rimmed cases and bulk 223 rem and use it to chamfer/deburr. The insurance co pay for having to go to the doctor will be more that what it costs.

Anyone here tried this one?

Try the Lyman Case Prep Center, a great machine that deburrs inside and outside along with cleaning primer pockets and making them uniform!

Have not, but note there is no mention of battery capacity nor rpm. But does state can also be used as a cordless screwdriver. So I would expect battery life and bit rpm very similar to a low to mid-level cordless driver like a Ryobi or Kobalt. Not that you need much at all, but on a drill it's literally as fast as you can lightly touch it to the tool and drop it in the bin. And even an inexpensive Li-ion drill like a B&D will have plenty of battery for a very large batch. I use this one https://www.homedepot.com/p/BLACK-D...-Battery-1-5Ah-and-Charger-BDCDD12C/300227309 bought it for my mom to start her gas trimmer but it isn't strong enough so she gave it back. I find it utterly useless....except it excels at chucking those Lyman bits and batch processing brass 500ish rpm is nice that it's fast enough but not so much it's easy to screw up and overdo it.

Added bonuses are the pocket reamer tools included with the Lyman tool - I've found those a lot faster taking out crimps than the super swage & can sit on couch watching TV. And the fat handle is easier to use for small batches or I do the inside chamfer with drill and mrs cmv does the outside debur with the Lyman tool since it only takes a half twist. Assuming you already own a drill of some sort, the Lyman tool with all the included bits is probably least expensive if that matters. If those bits can be bought separately (never looked) would be even cheaper, but the tool stores them inside so kinda nice just having whole thing.

I got one of those several years ago and returned it.

Not even one of the stations was rotating on a fixed axis (at least 2 were totally unusable) and, when I picked it up to put it back in its box prior to determining what to do with the silly thing, I found that it had taken a crap (looked like high-quality black grease) on the bench.

I talked to a nice Lyman CS lady and she was both not surprised and rather cavalier about the poor condition of the product.

Thank goodness I was still within (just barely) the Amazon Return Window. WHEW!

Perhaps I just got a Lemon.

I find it's best to handle the cases least as possible. I use a 3 way cutter, 1 step and done all 3 functions. I've also found that these type of cutters due best when spun in 800 rpm range. Fast enough to remove a lot of material if needed and does not want to bite and hang up (spin the brass in your hand).

This is what I use too. It also does a good job of containing the mess. Still, it’s a tedious process.

For trimming I use the WFT

 

[1KPerDay]

Apparently they don't make a 3way cutter in .357" and everyone is backordered anyway. Probably going to order the Hornady duo unless someone can give me a compelling reason not to. I already have primer uniforming, cleaning, and crimp removing tools.

 

[edwardware]

I have one of these (Lee chamfer tools). . .

I too started with a Lee tool. . . and they're terrible. The edge isn't sharp enough to cut efficiently, and the 45deg angle, while sensible, isn't what it should be.

I progressed to an RCBS double-ended, and once sharpened it's slightly better.

Then on to a steel VLD chamfer tool; now we're talking! 6 edges cuts faster, and the high angle is closer to orthagonal to the rolled burr you're trimming, and much faster! I use it outside too, because the angle is better.

I have since bought a carbide VLD tool, and it's slightly better for inside, but you can't do outside.

All this in the context of rifle brass, sometimes 500 at a time. My suggestion is to buy RCBS's steel VLD tool.

Also, for next time, a really sharp trim cutter tends to leave a thinner, more fragile burr; it's slightly easier to trim.

 

[1KPerDay]

Ordered the Hornady Duo. I had some amazon points so it only cost me $25. Should be way better than the Lee hand powered doohickey.

 

[30Cal]

I have a socket that my chamfer/deburr tool fits into so I can spin it with a cordless drill.

 

[1KPerDay]

Update. Hornady duo is great. Ran out of battery once but that was because I forgot to plug in the charger after a long session. Works really well so far.

 

[Herman B]

I don't have a lathe or drill press. What I need is a power drill with chuck jaws wide enough to hold the tool.

Here's an inexpensive and very effective solution: L. E. Wilson chamfer/deburr tool mounted in a Sinclair Case Mouth Deburring Tool Holder, about $33 total. Chuck it into your cordless driver. Use a rubber glove for better grip on brass, less finger fatigue.

I just might have to order one of those myself. Right now I used a hand-held L. E. Wilson tool.
