Which chamfering / deburring tool

[joojoobeans]

Hi guys,

Quick one... Do you reckon there is anything in which chamfering and deburring tool to pick?

Looks like it's a matter of angles on which one you pick?

Anything in it or just pick up whatever?

[RoginaJack]

Nope, I've used a Simplex for many years.

There seems to be a few flavours out there. A factor would be what volume you need to do. There's a couple of options that trim and chamfer at the same time, Lee Deluxe Trim is one. If you just want a simple chamfer tool, then whatever strikes your fancy I guess. Perhaps something you can hold in a drill/screwdriver chuck would speed it up.

Something with a handle over the lee or simplex one which is a pain in the....hand when doing bulk quantity of cases.

Lyman case prep kit looks ok

I use the little lee one but rarely do I need to trim.

I'm using the same RCBS one as deye243 pictured above.

Has worked find in the half dozen calibres I've used it for.

Only comment would be that if you dig too deeply with it you can create thin, sharp necks but that's user-error, not a bad tool.

A light touch, just enough to remove the bars, and it's absolutely fine. Easy once you've had a few goes and got a feel for it.

[deye243]

yep a tad less that a second on the drill works just dandy

I never new the shape of the tool was to let you put it in a drill. Cool.

Any of you do it by hand with the same bit? or is it too hard like that?

[Pilch]

It works by hand.

5-6 back and forths on the neck will do it.

[Lorgar]

Easy enough to do my hand, pucker.

I use the Lee Trimming system with the shell holder in a drill. Put the brass in, give it a spin with the trimmer, give it a spin with the dechamfer, drop it out and done.

Quite quick.

Are there any issues with using a VLD chamfer tool (very low angle to reduce bullet shaving) instead of the regular item?

In my observations bullet shaving problems come from people over chamfering the outside of the brass, not the angle of the inside.

Standard tools for the inside neck come in a range from 22 - 45 degrees or there abouts. Which ever option you go as long as you've removed all the burs they all provide a smooth funnel the bullet should slide into relatively easy.

The problem comes chamfering the outside with the 'fingers' end of a tool (the back end being held by deye243 drill).

A light twist to remove burs from trimming is fine. If you go to far though though you sharpen the end squeeze it in created a ringed blade rather than a funnel.

My 2c.... Trim the outside first lightly, then the inside to push the edge out away from the bullet. I've never give any worry to the chamfer angle personally.

I have use the RCBS demurring tool for many years and it works fine just using it by hand. It can be a bit tedious when doing several hundred at a time. I now have a Lyman case trimming kit, mounted to my bench. It is fast, affordable and built well. Just be aware to use a light touch as the cutter is nice and sharp and one or two rotations of the handle is all it takes to remove any burr. You can definatly feel the difference in case hardness after annealing. That cutter almost eats soft new brass.

Tedious maybe but doing by hand is easy enough.

Remember you're just removing burs, you're not really trying to do anything to the neck itself.

[deye243]

i never do the outside unless i have to trim my case's

[Boatman]

i never do the outside unless i have to trim my case's

Depends on the trimmer. I've seen a few fan a sharp rim outwards from the case that needs chamfering off.
