I'm looking for a deburring tool to debur some case necks. I'm stepping 223 brass down to 20 cal. I have a few hand held chamfer/debur tools, but the debur tools have never worked worth a darn. It seems like every "deburring" tool I've found are not actually sharp, and tend to just push the bur back instead of cutting it off. Normally, I use a scotch bright pad to debur after trimming to length, but I'm wanting to put a more aggressive external chamfer on these necks so they will feed into the smaller bushings more easily. Curious what others are using for this.
