- 7 Pilots & 3 Collets
The Forster Products CTK100 Original Case Trimmer Kit is a workhorse reloading tool built on proven bench-proven design. If you're trimming rifle or pistol brass and want a solution that's straightforward, reliable, and expandable as your reloading program grows, this kit gives you the core setup to start trimming cases accurately across most common calibers. The Original design is built around a Brown & Sharpe type collet system—the same precision approach used in miniature machine tools—so your cases stay centered and your trim lengths stay consistent.
What makes the Forster trimmer stand out is versatility without complexity. The kit ships with three collets and six pilots, covering bullet diameters from .171" to .459", which means it handles everything from .17 Hornet through .458 Magnum and most handgun brass in between. You're not locked into a single setup: as your cartridge collection expands, you can add collets and pilots individually without buying a whole new trimmer. That modular approach keeps your cost down if you reload multiple calibers.
The collet-based holder design means less fuss than some alternatives—no special adapters or workarounds—and the trimmer itself handles the actual trimming straightforwardly once you've dialed in your length. If you're building a reloading bench from scratch or adding a second trimmer to speed up prep work, the CTK100 is the kind of tool that earns its space through years of quiet, dependable service.

Frequently Asked Questions
What calibers does the Forster CTK100 trim?
The kit covers most rifle and pistol calibers with bullet diameters between .171" and .459". The included pilots—22, 24, 25, 27, 28, and 30—fit common cartridges in that range. For specific caliber fit, match your cartridge's bullet diameter to the pilots and collets provided. If you reload .17 caliber, you'll also need the Forster Trimmer Cutter w/Shaft 17 cal.
Can I use this trimmer if I reload multiple calibers?
Yes. The CTK100 is designed to be expandable. The kit includes collets #1, #2, and #3, and the Original trimmer accepts collets #1 through #4. As you add different cartridges to your reloading bench, you can purchase additional collets and pilots to fit them without replacing the trimmer itself.
What's included in the kit?
The CTK100 ships with three collets (#1, #2, #3) and six pilots (22, 24, 25, 27, 28, 30). These are the collets and pilots needed to trim a broad range of rifle and pistol brass. Additional collets and pilots are available separately if you expand to other cartridges.
Is this trimmer suitable for precision reloading?
The Original Forster trimmer uses a Brown & Sharpe type collet system, the same design principle found in precision machine tools. This collet design holds cases centered and allows consistent, accurate trim lengths across your brass prep work.
