Seriously these are the best inside and outside neck deburr tools ever.

I have been so frustrated with the poor quality of the neck deburr tools offered to hand loaders and now I've found some products that work very well on Amazon.

Get the 1/8"-3/4"... Now I don't see it shown any more, but I got the one with tungsten blades.

There are others if you shop around for better pricing, but I really like the carbide one.

Also pay attention to the angle, you don't want one on too soft an angle.

For accuracy I find that a really soft angled chamfer on the inside of the neck really helps get the bullet started when seating.

I've never tried deburring by hand.

I prefer the 21st Century 3-way trimmer upgrade for their neck turning lathe. Fast, efficient, and consistent. Well built and the micrometer is spot on.

Prior to buy one, I used to use the RCBS 3-way. It was good and consistent, but was a PITA to change out and set up.
 
I use the rcbs 3 way cutter on the trim pro 2. Love it.

I dont recall it being hard to set up, but I mostly just shoot one caliber, if I shot a mix of calibers I'd look into a different one.

The hornady version looks like it would be easy to swap over calibers.

The outside one is expensive if you don't use it much but does fit in a drill but the inside burrs are cheap and I own already so its a plus.

My regular rcbs/wilson deburring chamfer tool fits in my mini hobby lathe, works fast and good enough for me for now.
 
Never thought about using that tool for preparing brass, but why not.
One like it just happens to be on sale at Princess Auto, and includes the ID as well as the OD pieces.

I just use the bullet shaped RCBS hand tool for outside and and a Lyman VLD style taper hand tool for the inside. Never had a problem but I don’t shoot high volume 223 for example. Could always cut the Lyman tool handle off and chuck it in a drill.
 
I use the "Lee 3-Jaw Chuck" in my drill to insert and spin the cases. I use the old RCBS hand held chamfer and deburring tool on the spinning cases, but that still leaves a burr and sharp edges. So I follow with spinning the case with steel wool before removing it. The steel wool spin makes a nice polished finish on the case mouth.

I learned to wear a work glove on my hand for pressing the chamfer and deburr tool and steel wool into the spinning case. Before I learned this, one time I slipped with the chamfer tool and the spinning case mouth gouged a nasty slice deep into a finger. And don't forget the eye protection either!
 
The only issue I see with power deburring is that it is very easy to go too far, especially with the inside tool. Deburring only requires a minor touch to take the burr off. I find the outer is more difficult to accomplish with my old RCBS hand tool.
 
All honesty, I used the little RCBS hand tool for so many decades with no problems. When I started making thousands of loads with all my loading buddies in my shop I bought an all-in-one case trimmer machine and never looked back.

I still use the little hand trimmer tools all the time because sometimes its only one case or primer pocket and not worth finding drills or changing bits in power tools/machines.
 
Forster "3 in 1" and a small cordless drill, super slick and fast. Only have to handle the case once instead of 3 times. Cuts are super neat and precise.
 
Could one self adapt a Forester 3 in 1 cutter head to a Lyman case trimmer? Thats my only gripe with the Lyman as it leaves an interior and exterior burr after taking the cases down.

The lyman shaft is a bit too big in diameter for the forster 3 in 1 cutter so if you want to do this you either have to machine the hole bigger in the cutter or reduce the diameter on the end of the lyman shaft.

Making an adapter for inside the cutter that screws into the lyman shaft (7/16-20 thread I think) is another option that could work provided your brass still fits in the trimmer since the head is longer.
 
I used the RCBS double ended tool for many, many years, then switched to a nice Lyman inside reamer and used it for a few years. Today, I stopped in at Princess Auto in Regina and bought the set pictured above. I have two battery drills that are pretty much useless, so I'll leave them in my playhouse office where I do my reloading. I'll put the reamers in the drills and leave them near the charger. :d
 
Always wanted to by the 3 in 1 adapter for my Forster but I never did, so Im still using that RCBS little tool that came with the kit.
