This is a great tool, very easy to use. It gives repeatable results each time and, at $11, it costs about half what some other (less effective) deburring tools cost. Moreover, it is self-adjusting, and you can switch the cutting tip between small (for 6PPC/6BR) and regular (for standard diameter flash-holes). The deluxe "professional" version with a metal handle is available for $15.
|Note: This tool is primarily recommended for those people using Remington brand 6BR brass, 6XC brass, or other calibers like 22-250. We recommend that you leave the Flash-Holes alone with Lapua 6BR and 220 Russian brass (used for 6PPC). The Lapua 6BR cases come with a .059" Flash-Hole, and the K&M tool will ream the holes to approximately .064-.069" depending on tolerances. This can be useful if you must use a 1/16" (.0625") standard decapping rod. However, the best thing for Lapua 6BR brass is to use a die with a .057" decapping rod, such as the Redding, Wilson, or Harrell's.|
Using the tool is simplicity itself. Just feed the cutter into the case until the tip exits the flashhole and the cutter depth-stop contacts the inside base of the case. Then, holding the sliding cone against the case mouth with your first two fingers, give the knob a twist or two. It's fast, precise, and pretty much fool-proof. You can't ream too deep because a ring around the cutter tip bottoms on the case interior before you go too far.
With that quick turn or two you simultaneously "ream", "de-burr", and "chamfer" the inside of the flash hole. One great feature of the K&M tool is the "pre-set" depth stop surrounding the steel cutter. Because cutting depth is set off the inside of the case, not the case mouth, you can deburr cases of any length--they do NOT have to be trimmed to length first. And with the handy sliding centering cone, you don't have to fiddle with set-screws on cutter depth stops or buy different pilots for different calibers. The simple two-way sliding metal cone keeps the case aligned and centered as you deburr and slightly chamber the inside lip of the flash-hole.
