Been using this tool for years 10/10 !

[@hobbeeswe7472]

Instant trust and just the info I was searching for, thanks !

[@kmshooting]

Glad to hear!

Unlike my Lyman flash hole uniformer, this tool indexes inside the web of the case, not its mouth. Smart design. I’ll definitely buy one. I hope they are in stock.

Hey Rodolfo, thanks for the comment on the design; registering on the case-web provides much more consistent results. We've working hard to keep all flash hole tools in stock (even though they're very popular) and aim to ship next business day.

@@kmshooting thank you for the reply. I noticed you offer different sizes of tools. Which tool do you recommend to determine the correct flash hole diameter of my brass?

[@kmshooting]

First you need to determine your flash hole size(s).
The flash hole can vary depending on the brass manufacturer and doesn’t necessarily follow the primer size. Many use the “standard” .080” flash hole while Lapua can have a small flash hole .059”/1.5mm.
We recommend checking with a drill bit, shank non-cutting side, to determine which size you have:
 .08 flash hole: 5/64” (.0781”) drill bit
 .059/1.5mm flash hole: a 1/16” (.0625”) or #54 (.0550”) drill bit
Another option is measuring your de-capping/de-priming pin. If the pin is larger than .06” and fits loosely in the flash holes - you’ve got .08” flash holes.
We recommend the .062" for small flash holes and the .082" for large flash holes. Here's a little more info:
Premium .059 vs Pro/Premium .062
• Premium .059 vs. .062 comes down to opinion:
o The .062 will provide uniform hole size for “1.5mm” (.059) flash holes by opening the flash hole by .003”
o The .059 will chamfer the hole, clean up undersized flash holes and leave any oversized flash holes as-is
Pro .080 vs Premium .082
• The Pro cutter is an off-the-shelf center-drill sized at .080”
• The Premium cutter is a K&M carbide cutter
o The .082 will provide uniform hole size for flash holes by opening the flash hole by .002”
o The .080 will chamfer the hole, clean up undersized flash holes and leave any oversized flash holes as-is

@@kmshooting Thank you very much

[@riflegus]

Great video, cuestion for you please,
I already have determined the flash hole size, I'm about to purchase a 0.82 premium .
If later on I'll buy different brass as lapua, etc, which has smaller hole.
Can i just run the 0.82 through and make the hole bigger? Will this affect the brass? Or will I need to buy a 0.59 cutter?
Thanks

[@kmshooting]

Hey Gustavo, we recommend getting the .062 (or .059) for the smaller flash holes. We dont have durability data on using the .082 to open up the smaller flash holes - this would be at your own risk of possibly breaking the tip (or not).
A safer option - if you want to stick with just the .082, is to drill-out the small flash holes with a 5/64 or #47-48 drill bit before using the .082” cutter. We have several customers who do this and found better performance, BUT there are many factors that effect results so we don’t offer a recommendation either way.

[@jonbraddock5545]

How do you determine which size to get? I am working with mainly Federal commercial 308 brass with

[@kmshooting]

Hey Jon - these likely have the "standard" .080 flash hole. So, go with either the professional .080 or the premium .082.
