RCBS offers two neck turner attachments that work with the Trim Pro Manual Case Trimmer. The neck turner attachments each have a cutter unit that supports the cartridge case neck with a caliber specific pilot/reamer (see chart) while cutting. The pilot/ reamer enables the user to turn both the inside and outside of the case neck simultaneously. The RCBS Neck Turner w/Auto Feed attachment option allows for smooth and even advancement of the cutter with each turn of the trimmer handle. Pilot/ reamers are sold separately.
NOTE: Not to be used with the Trim Pro Case Trimmer.
