The Universal Precision Case Trimmer is the same great technology found on the Platinum Series Case Prep and Trim Center, however, it is designed to be used with a standard drill or mounted in a drill press. Unlike conventional trimmers, the Universal Drill Trimmer requires no caliber specific pilots or shell holders. The included collets index off the case shoulder to trim any shouldered case from 17 Remington to 460 Weatherby Magnum. Simply install the correct collet, adjust the trimmer to your desired length, then secure the trimmer into a drill or drill press. Cases are then fed into the trimmer by hand. With a little practice, the Universal Drill Trimmer will trim cases faster than any traditional trimmer you've ever used.
