Lyman’s new power adapter allows you to quickly and simply convert your Universal Case Trimmer to a power trimmer. All you need is a standard electric hand drill or power screwdriver. The adapter comes with its own cutter and stop collars so you can convert back and forth from power to hand mode without changing your settings. You can easily trim over 250 cases an hour in the power mode. The Lyman Universal Chuckhead system allows you to switch to any caliber from .17 up to .458. No collets required. The power adapter fits only the Lyman Universal Trimmer.
