K&M Case Neck Chamfer Tool (Tapered Reamer) 6mm - .338

The K&M Case Mouth Chamfer Tool cuts a shallow angle chamfer on the inside of the case neck for smooth bullet seating while controlling the depth of cut with stop fingers that register on the case mouth which insures each case has the same depth chamfer. The chamfer angle is 4 degrees per side. The tool also incorporates a pilot pin that guides through the flash hole of the cartridge to maintain the tool on the centerline of the cartridge for an even cut.The tools cut chatterless by means of a 6-flute cutting design except for the .17cal-6mm tool which is a 3-flute tool.
