Description
Case prep is the part of reloading that separates ammo that shoots well from ammo that just goes bang, and the Lyman Case Prep Multi-Tool makes that work a whole lot easier to stay on top of. Instead of scattering a handful of loose deburring tools and primer pocket cleaners across your bench, Lyman packs the essentials into one knurled handle that unthreads in the middle so every bit lives inside the tool when you're done. It's a simple idea, but anyone who has lost a small primer pocket reamer in the carpet will appreciate it.
What the Lyman Case Prep Multi-Tool Handles
The set covers the four jobs that come up on nearly every brass prep session. You get an outside deburring tool and a VLD inside deburring tool for cleaning up case mouths after trimming, plus large and small primer pocket cleaners and large and small primer pocket reamers for scrubbing out carbon and sizing crimped pockets on military brass. Chamfering a freshly trimmed neck and knocking the crimp out of a primer pocket both go quickly with this one in hand.
How the Double-Ended Design Works
Both ends of the handle are threaded, so you can mount two heads at once and flip the tool end over end as you move from one step to the next. That means you can run it as a single two-sided tool or break the heads off and use them separately when it's easier to spin the bit by hand. The handle itself is bigger and more substantial than it looks in photos, which gives you plenty of grip for the pushing and twisting that case prep demands.
Reloaders tend to like this one because it keeps everything together and does real work without a motor or a bulky prep station taking up bench space. It's a grab-it-and-go piece of kit for folks loading rifle and pistol brass who want solid results without overcomplicating the process.

Frequently Asked Questions
What tools come with the Lyman Case Prep Multi-Tool?
It includes an outside deburring tool, a VLD inside deburring tool, large and small primer pocket cleaners, and large and small primer pocket reamers. All of the bits store inside the handle, which unthreads in the middle so nothing gets lost on the bench.
Can the Lyman Case Prep Multi-Tool use two heads at the same time?
Yes. Both ends of the handle are threaded, so you can mount two heads at once and simply flip the tool end over end as you move between steps. You can also pull the heads off and use them individually if that's easier for a given task.
Does this tool work for both rifle and pistol brass?
It does. The deburring heads clean up case mouths after trimming, and the large and small primer pocket cleaners and reamers handle both primer sizes, which covers common rifle and pistol calibers. The reamers are especially handy for sizing crimped primer pockets on military surplus brass.
Is the Lyman Case Prep Multi-Tool hand operated or does it need power?
This is a hand tool with no motor required. The knurled handle gives you good grip for the twisting and pushing that case prep involves, and it's larger and sturdier in person than photos suggest. Some reloaders also chuck the threaded bits into a drill for faster work on larger batches.
