Battenfeld Technologies, Inc. Platinum Series Case Prep & Trim System is highly accurate and capable of trimming brass within seconds. Included is a sleek case holder with adjustable collet and bushing system. This system trims brass to an exact and preferred length. After adjusting the holder by inserting brass, a collet aligns squarely with the high-speed cutter. The mouth contacts the cutter, trims, and then stops on an internal bushing. There are three separate collets and six bushings included in this system designed to accommodate case holders, such as .17 Remington and .460 Weatherby, and everything in between.
