For reloaders who already use Lyman’s original Universal Trimmer, this adapter adds a straightforward way to move from hand trimming to drill-powered trimming. It replaces the existing trimmer shaft and includes its own cutter and stop collars, allowing the setup to switch back and forth between power and hand operation as needed. The design is aimed at higher-volume case trimming, with the stated capacity to trim over 250 cases an hour. It is made specifically for the Lyman Universal Trimmer, so compatibility should be confirmed before purchase.

Pros

  • Converts a Lyman Universal Trimmer to powered case trimming with a drill
  • Advertised capacity of over 250 cases per hour
  • Includes its own cutter and stop collars
  • Allows quick switching between power and hand operation
  • Economical option for reloaders who already own the original Universal Trimmer

Considerations & Trade-offs

  • Only compatible with Lyman’s original Universal Trimmer, so it is not a universal upgrade for other trimmer models.
  • Requires a drill for power trimming, so it adds a tool dependency rather than replacing the need for one.
  • Designed to convert an existing hand trimmer to power operation, which means it is an accessory rather than a complete trimming system.
  • Includes its own cutter and stop collars for switching back and forth, but that also means setup changes are part of moving between power and hand use.
