Help on Deburring Tools

I currently use a Sinclair/Wilson case trimmer. What inside and outside case deburring tools do you guys like? Please don't tell me to get a Girard or a Henderson. I know all about them and one is on the list but for now my S/W works just fine but my deburring tools are dull and I'm having problems. What do you fellows use?
 
jg,

I use the Lyman wood handled inside deburring tool on both the inside and outside edgers. Follow up with 4-0 steel wool around a brush on match cases. Not trying to remove a lot of brass, just enough for a smooth seating.

HTH,
DocBII
 
Have you ever tried this one?

It is more of a tapered reamer with a center and depth stop, it is generally a hand tool but it too can be powered. This is what I like to call the nuclear solution. If there is an ID chamfer issue, this should kill it.

All of the ones above should work no problem, but I thought I would point this out in the case where you hadn't seen it.
 
I have tried most and wound up with the K&M as it is the only one that pilots off the flashhole and will make an even inside chamfer from case to case. it is adjustable so you can adjust chamfer angle to match your bullet shape. and cutters are super sharp.
Con is it takes longer per case.
Outside de-burr is best using a quality tool that has really good cutters that stay sharp. I like the wilson one.

All above for precision loading...for regular anything decent works fine.
 
Not fancy but works and is economical = RCBS handheld deburring tool. Been using it for 50+ years.

No need to complicate chamfering the necks after trimming. A twist inside and outside is all that is needed. Now I did it, someone is going to post a thread with test data that shows you have use tool XYZ or bad things are going to happen!

this is another area where shooters over think things.

Like you, I have been using my old RCBS chamfering tool for 50+ years.

Granted, it is not “blue tooth” capable, and does not require a battery pack. But it gets the job done ;)
 
Before I started using a 3-way tool, I was not happy with how chamfering by hand was not leaving the chamfer square to the neck and contributing a lot to bullet runout. This is not an issue for a lot of reloaders, but for me, I want that chamfer cut as square to the neck as possible. The Giraud solved the issue for me. :)

Anyone remember the Brass Barber? That was a 3-in-1 tool that used HSS cutters. I think I got mine back in the 80’s. Think the company was Monadnock Machine in NH.

If you own a drill press, vertical mill, lathe, or anything that moves and stops precisely; mount a Forster or Henderson 3-in-1 tool in said machine, along with a Lee case holder held in a vise, and trim brass the easy way.

You're welcome, enjoy.

Yes, though I run it with the 1/4" drive that they make with either my Hornaday "Case Prep Duo" or just in a 1/4" drive screwdriver {slower than a drill}
I must say that the Hornaday Case Prep Duo is the handiest tool as I can quickly lightly de-bur case mouths after wet SS pin tumbling {always a factor, especially for small, lightweight cases such as .223 or 6BR}
Tumbling can slightly peen the case mouth and if you don't de-burr them you can wind up with a slight trumpet mouth when seating you bullets and wind up at the range with rounds that will NOT chamber...!
Been There... Done That....!
Amazon through all the major suppliers to our hobby have them just under $50...! Best bit of kit for the $ and you can sit and watch TV with a tray in you lap to catch the brass shavings... {:~)
despite the picture showing it as a straight inline tool this has a rotating handle that turns into a pistol grip.
The KM tool goes in after sizing and before priming... It truly cuts a perfectly referenced chamfer at 17* for just that easy start of seating your projectile.

Yes it does... As long as you hand and fingers hold up... Moved up to a Hornady "Case Prep Duo" and love it as it is waaay quicker than the old manual "rocket ship"...
