The RCBS Trim Pro Case Trimmer Cutter Head (model 9406) is the replacement cutting element for handloaders running the Trim Pro case trimmer system. It's the same cutter head RCBS ships with the Trim Pro from the factory, so there's no fitting or modification needed to drop it into your existing setup. If your original head has dulled after thousands of cases or you keep a spare on the bench for high-volume sessions, this is the part you want. It trims fired brass back to consistent length, which is the foundation of safe, repeatable reloads across rifle and pistol calibers.
The 9406 is machined from steel and finished with a hard coat black anodized treatment, per RCBS specifications. The head is designed to return brass to SAAMI specifications and spaces to minimum tolerances, which is what keeps your trimmed case length uniform from the first piece to the last. Because it's the factory-spec cutter, it indexes into the Trim Pro shaft without shimming or adjustment. It also works with RCBS rotary case trimmers. A sharp cutter head matters more than most reloaders realize: a worn edge drags, leaves a rough mouth, and forces extra chamfering and deburring work to clean up afterward. Pair fresh trimming with a quality chamfer tool and you cut step time considerably.
Reach for this head when your trimmer starts leaving torn or burred case mouths, or stock one ahead of a big brass-prep run so you're never stopped mid-session. It's made in the USA and fits directly into the Trim Pro you already own. Many shooters keep a spare alongside their pilots, collets, and deburring tools so a single dull edge doesn't shut down the bench.

Yes. The 9406 is the same cutter head RCBS ships with the Trim Pro, so it indexes directly into the trimmer shaft with no fitting or modification. It is also compatible with RCBS rotary case trimmers.
It is machined from steel and given a hard coat black anodized finish per RCBS specifications. The anodizing protects the cutter body, while the steel cutting edges do the work of trimming brass to length.
The head is designed to return brass to SAAMI specifications and spaces to minimum tolerances. That keeps your trimmed case length uniform across a batch, which supports consistent, safe reloads in both rifle and pistol calibers.
Replace it when the trimmer starts leaving torn, dragged, or rough case mouths instead of a clean cut. A dull edge forces extra chamfering and deburring work. Many reloaders keep a spare 9406 on the bench before high-volume prep sessions.
The RCBS 9406 cutter head is made in the USA per manufacturer specifications.
