Re: Clogged Flash Hole Deburring Tool
I use mine with a manual handle, and tap the shaft on the edge of the bench occasionally. Works about as well as I need it to.
Besides, I like the hand reaming process; I believe the sense of touch has a genuine value there.
I had a collar slip once with the drill motor and ruined maybe 20-30 cases before I caught it. The flash holes got way oversized, and primer pressure signs got really weird. Those cases could not be made to shoot well.
