Best flash hole debur tool?

[DngBat7]

What is the best flash hole debur tool? The clincher is I don’t want to shave the actual flash hole, just the burrs. Small primer lapua brass .059 and don’t want to expand them.

 

[DngBat7]

Not big. I just want a good one for all my brass across the board. But I also don’t want it to ruin my expensive brass by making the flash hole bigger. The rcbs looks interesting in the way it works, but most of these tools seem to drill out the hole

I don’t touch the flash holes. Any burs that might have been there are gone after fireforming.

I like these.

if you use a reamer to uniform the flash holes there is no burr.... most of the time. if you see one just take it off with a K&M manual deburring tool or something similar... do not chamfer it.... jim

If you buy good brass you don't need it. I'm not convinced they help bad brass either. But even if they do, you're better off buying good brass. It's cheaper in the long run.

The K&M manual .059 is a good one....will touch up the burrs and give a consistent bevel.

You may be looking for a problem that isn't there

Not like lookin for a problem persay. Just from what I have learned from this site you want everything as uniform and concentric as possible from case to case. But if all you say it’s a waste, so be it. I’ll skip that step

The K& M tool is the cats pajamas for this process

A lot of reloading tools sold are in need of a problem.

The one I use (as a station on RCBS Prep center) indexes depth via case length. So, if I ever do 'deburr', it's a one time thing, done right after trimming a batch of brass to uniform size. Which is done after the first firing. So, at least there's some assurance of consistency, from soup to nuts. And since I'm doing chamfer/deburr necks on Prep Center anyway, it's only another 2 seconds (per case) to use the flash hole tool, too...

Anymore, when loading 'good stuff', I don't even bother. Something about flash holes being drilled in 'good stuff', vs. punched/stamped in the 'cheap stuff'.

With 'cheap stuff', seems like the amount of 'deburred' material varies from each individual case? That tells me, there is some benefit to uniforming/removing a 'burr' from that area. Might not actually matter in real life, but makes me feel better to know that some material, which may have (potentially) been impeding consistent ignition, has been removed...

After prepping 40 pieces of lapua, I'm almost ready to say messing with the flash hole is a waste of time on their brass.
Remington, nosler, hornady, federal well now that's a different story. Those holes be rough!

After doing 1000s of Lapua brass I thinks it's very necessary . Get a good tool and you can feel every burr in there . Lapua is great stuff but the brass on my bench when I tap the case shows me they are not perfect. Just my findings.

Oh I got a lil trimmings, but very little.
The other brass I mentioned above was lumpy, bumpy, rougher n cobb.
The lapua felt really smooth, I believe the lil bit of shavings were from putting a lil camphor on rim of hole.

Well. I also realized the other day I was getting much bigger chamfers than I wanted in some cases. Then I realized the cases should be trimmed exactly the same before deburing. Non trimmed cases will have different depths. Brain fart

I take the time in prepping from uniforming the primer pockets , flash hole uniform to the same size testing with a #45 drill bit for 308 caliber , deburring flash hole inside an a light taper outside . Only has to be once . I also trim every time , after the first time trim , most of the next trimmings are more like a clean up rather then a trim . All are full length sized to .0015 - .002 no more or less . I wet tumble using SS Pins with Sun liquid detergent , brass every time looks brand new .

Lyman makes a nice tool. It is pretty much a tappered drill bit with an adjustable collar to set depth of cut. This should work for you.

Nope,I am using my fingers,not a lathe . Not hitting those burrs hard enough to even start a chamfer . K and M is a marvelous tool if you use common sense.

RCBS Flash hole deburring tool works just fine . Any Primer pocket Uniformer and your ready to go .
