Deburring tool

[Dot3]

I have a case prep station and need a better outside chamfering head. I’ve gone through two that didn’t do a good job. The standard Frankfort arsenal head and another, I can’t remember who made it. What’s happening is it’s actually creating a lip around the rim. Like it’s rolling the edge over to the outside. Is there a quality cutter anyone recommends that threads into a prep station?

I probably over think and over do it but I let my Girard deburr as it trims and then just prior to loading I run my brass through the tool from Worlds finest trimmer, I have a manual version that is pretty fast and handy but I wouldnt be surprised if they offer heads for prep stations.

The Lyman VLD tool fits in my RCBS Case Prep station, and works pretty well for me.

I also have the RCBS prep station and swapped out the inside deburr tool with the Lyman. 100% better than the RCBS tool.

Yep they do have tools that screw into a prep station. Will give it a try. Thanks

Will have a 3-way cutter before it’s all said and done, but in the meantime-gotta figure something out

The inside chamfer isn’t a problem. It’s the outside chamfer. I should have been more clear. I’ve worn two out in short order. Wouldn’t think I’d wear them out but they used to leave a chamfer now they just leave a lip.

Since you need the outside tool, I'd look around to see if someone makes a carbide one that will fit on the prep center. It will be expensive, but may be what you need.

Well, then I think what you're looking for probably more correctly termed a 'deburring' tool. Chamfer on the inside of the case mouth to ease the bullet transition into the case neck, deburr on the outside to eliminate any sharp corners catching on things during feeding. Lyman offers one of those as well, generally made to the same standard as their VLD chamfer tool.

That said... sounds like you might be applying a *bit* too much pressure, if you're wearing out the deburring tool(s). Literally all you need to do is touch it to the spinning head for a couple seconds. Don't lean on it

Yeah, just wondered if someone knew of one off the top of their head

The title and the body stated “Deburring” until I edited the body bc of the recs for chamfering tools. To your point about adding too much pressure, I’ve tried light pressure, heavy pressure, long dwell time, short dwell time. It no longer works. I chamfer before every loading but only deburr after a trim and there’s a definite burr. Used to be the tools I have removed the burr but they quit working. Maybe the burr is bigger because my trimmer head is worn out and chattering.

Hmm. Will have to take a closer look at that

 

[memilanuk]

Huh. Usually when the tool starts cutting poorly, yeah, a new (sharp) one is called for. If your trimmer is leaving a big nasty burr even when trimming after every firing, then maybe the cutter on your trimmer needs looked at.

I had fits for a while with my Giraud - but only in one caliber/cartridge (308 Win). Turned out, I'd worn out one set of cutters on the triangular head. I *thought* I'd rotated the cutter, but I still got big nasty burrs. Eventually I figured out that yes, I had rotated the cutter, but I'd let things bang against each other in storage, and managed to screw up the edge on the second cutter - even though it was carbide. Finally just got a new cutter, and everything worked again. Oh, and I make damn sure to wrap the cutter in something before putting it back in the drawer.

Not sure if any of that applies even tangentially to your situation, but maybe. I just don't know that getting a carbide deburring / "outside chamfer" tool is going to be fixing whatever the underlying real issue is.

Good luck.
