RCBS Trim Pro Power Case Trimmer Steel Cutter Head 9406

Description

A sharp cutter head is the difference between smooth, square case mouths and chatter-filled trims that need extra cleanup. This is the RCBS steel replacement cutter head, part number 9406, built to fit the Trim Pro line of case trimmers. It's the exact same cutter that ships with the trimmer from the factory, so there's no guesswork about fitment or performance. When your original has seen enough brass to dull down, this swaps in and gets you back to crisp, repeatable cuts.

What the 9406 Cutter Head Does

The steel cutting head trims your cases down to a consistent length so every piece of brass in your batch measures the same. Uniform trim length matters for feeding, chambering, and overall consistency on the bench, and a fresh cutter keeps those edges clean instead of leaving a ragged mouth that needs heavy deburring. The 9406 is the standard steel version, which handles typical reloading brass without complaint.

Fitting the Trim Pro Cutter Head to Your Setup

Installation is about as simple as it gets. You remove the worn cutter from your Trim Pro and thread this one into place, and you're ready to run again in a minute or two. It works across the Trim Pro and Rotary trimmer family, so if you're running one of those presses, this is the drop-in piece you want on the shelf as a spare.

Steel or Carbide Cutter Head

RCBS offers this cutter in both steel and carbide. The 9406 is the steel option, the one that comes standard on the trimmer and does the job for most reloaders working through normal volumes of brass. If you trim in huge quantities and want something that lasts even longer, the carbide version is the step up, but plenty of folks run the steel head for years and never look back. Made in the USA and backed by RCBS, it's a smart spare to keep handy so a dull cutter never slows down a loading session.
