The universal precision case trimmer is the same great technology found on the platinum series case prep and trim centre, 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 shellholders. 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. Adjustable collet system works with all shouldered cases from 17 Remington to 460 Weatherby Dual bearing system allows outer housing to float (not spin) while in use Works with almost any 1/2 inches drill or drill press Ultra-hard HSS cutter will stay sharp for thousands of rounds Micro-adjustable Universal collet system indexes on case shoulders for precise and consistent trimming every time
