The power pack combo is an innovative solution that seamlessly integrates Lyman's power adapter with the universal case trimmer, enabling a swift transition from manual to power trimming. Designed for efficiency, this combo requires only a standard electric hand drill or power screwdriver to operate. The conversion process is straightforward: unscrew the cutter head from the standard shaft, remove it from the trimmer, insert the power adapter shaft, reattach the cutter head, and connect your drill. This setup allows you to power trim over 250 cases per hour effortlessly. The adapter shaft is equipped with its own cutter and stop collars, facilitating easy switching between power and manual operation without altering settings. The patented Lyman universal chuck head system enhances versatility, accommodating calibers from .17 to .458 Cal without the need for collets. Additionally, the package includes nine of the most popular pilots, ensuring comprehensive support for a wide range of trimming needs.
