I am interested in finding a flash hole deburrer for 6.5×47 Lapua brass. I suspect that the new PALMA brass with small rifle primer pocket will have the same dimensions and issue. Anybody interested?

Seems missed math check, 19/32 = 0.59375, not 0.059375.
2. I am trying to reach a supplier that has drill blanks (hopefully that means no cutting flutes) – http://www.buydrillbits.com/products/hss/gp2.php?c=DRILLBLANK#DB55 – they list both the #53 (0.0595) and the next smaller (#54 at 0.0550). Seems one of them might work if it is actually possible to “push” out the burr.
3. I contacted K&M by phone re their tool on 2/10/2010 – http://www.kmshooting.com/catalog/flash-hole-uniformer-tools/flash-hole-uniformer_professional-ppc_0062.html. Response – the pilot is spec’d at 0.062 BUT may be as large as 0.064 (in which case some material may be removed).

Incredible to me after almost three YEARS that an appropriate tool has yet to be developed. If there is one, please provide info.

1. Thanks for heads up. Removed 19/32 reference!

2. eHobbytools.com has a 1.5mm pin vise bit. That matches the Lapua spec. YES it is definitely possible to push or pop out the flake with the right sized pin vise bit. Just push and spin quickly to remove obstructions without increasing the whole size.

3. You’re right, most of the tools on the market are spec’d to 1/16 (.0625) and we’ve seen them cut up to 5 thousandths larger.

I sent it back. I’m still looking for a deburring tool that wont enlarge the flashhole.
