Lyman Universal Trimmer - Power Pack Combo

The Lyman Universal Trimmer Power Pack Combo transforms your reloading workflow by giving you the flexibility to trim cases by hand or power—without buying separate equipment. This two-in-one system pairs Lyman's proven Universal case trimmer with a power adapter shaft, so you can switch between manual and electric trimming in seconds. Whether you're processing a handful of brass at the bench or running high-volume batches, this combo adapts to your pace and workload.

Power trimming is where this system really shines. Once you've converted the trimmer to power mode—a simple swap of the adapter shaft and a quick drill attachment—you can process over 250 cases per hour. Any standard electric hand drill or power screwdriver works as the motor, so you don't need to invest in dedicated reloading machinery. The power adapter shaft includes its own cutter and stop collars, meaning you can switch back to hand trimming without losing your caliber settings or needing to readjust anything.

The heart of the system is Lyman's patented Universal Chuckhead design, which accepts cases from .17 caliber all the way up to .458 without requiring collets. The combo ships with 9 pilots covering the most common calibers, so you're ready to start trimming straight out of the box. Whether you're a high-volume reloader or someone who values flexibility and space-saving versatility, this dual-mode trimmer eliminates the need to choose between speed and simplicity.
