Description
If you've ever cursed through trimming a few hundred cases on a hand-crank setup, the Frankford Arsenal Universal Precision Case Trimmer is the kind of tool that changes your whole prep routine. Instead of fiddling with caliber-specific pilots and shell holders for every cartridge you load, this trimmer uses a collet system that indexes directly off the case shoulder. You chuck it into a drill or mount it in a drill press, feed your brass in by hand, and let the motor do the grunt work.
What Sets the Universal Precision Case Trimmer Apart
The collet system is the heart of this thing. The included collets and shoulder bushings cover shouldered cases all the way from .17 Remington up to .460 Weatherby Magnum, which is a huge range for a single tool. Because it references the shoulder, you skip the shell holders entirely. A built-in depth micrometer lets you micro-adjust to your exact trim length, and the high-speed hardened stainless cutter is built to hold its edge through thousands of rounds. There's also a brass shaving ejection port that keeps chips clear of your work so you're not constantly stopping to clean up.
Running Brass With the Frankford Arsenal Case Trimmer
Setup is straightforward: install the right collet for your case, dial in your length, lock the trimmer into a 1/2-inch drill or drill press, and start feeding cases. With a bit of practice, you'll move through a pile of brass noticeably faster than any manual trimmer. The feedback from folks who run it is consistent on one point: steady, even push pressure gives you the most uniform case lengths, so check a few with your calipers as you dial things in.
Built to Last
It's made from real steel rather than flimsy pot metal, and everything tucks neatly into the included plastic storage case so your collets and collars stay organized between sessions. For anyone loading multiple calibers or working through high-volume brass, it's a genuine time-saver that earns its spot on the bench.

Frequently Asked Questions
Does the Universal Precision Case Trimmer come with a drill?
No, the drill is not included. The trimmer is designed to chuck into almost any 1/2-inch hand drill or drill press, so you'll supply your own power source. This lets you use whatever drill you already have on the bench.
Do I need caliber-specific pilots or shell holders with this trimmer?
No, and that's the whole point of this design. The collet system indexes directly off the case shoulder, so there are no pilots or shell holders to buy or swap out. The included collets and bushings cover shouldered cases from .17 Remington all the way up to .460 Weatherby Magnum.
Can the Frankford Arsenal case trimmer handle straight-walled cases?
No, it only works with cases that have a shoulder, since the tool references that shoulder for its length and consistency. Pistol brass and straight-walled rifle cases won't work with this system. For bottleneck rifle brass, though, it covers a very wide range of calibers.
How do I get consistent trim lengths with this trimmer?
Use the built-in depth micrometer to dial in your exact length, then feed cases with steady, even push pressure. Checking a few cases with your calipers as you start helps you confirm your setting. Once it's dialed in, it trims a high volume of brass quickly and uniformly.
