Add 3-Way Case Mouth Cutter to Your Forster Trimmer

three-way three in one cutter

We know many of you guys have a Forster case trimmer (hand lathe) sitting on your reloading bench. This tool does a good job of trimming cases to length. But did you know that an inexpensive accessory will allow your Forster case trimmer to chamfer while it cuts? Here’s the skinny on the 3-way head for the Forster case trimmer.

Tool Cuts Brass to Length, and Chamfers Inside and Outside
Forster’s 3-in-1 Carbide Case Mouth Cutter works with all existing Forster case trimmers. This unit does three jobs at the same time. It trims the case to length, it puts a 14-degree chamfer on the INSIDE of the neck, AND (last but not least), it cuts a 30-degree chamfer on the OUTSIDE of the neck. It does this all quickly and efficiently — in a matter of a few seconds. We tested the new tool ourselves on a few cases. The tool is solid and well made. The carbide cutting tips do perform a very clean cut. Be aware, however, if you have turned your necks already, you may have to reset the blade positions before you start trimming your brass.

Forster’s CFO, Robert Ruch, demonstrates the 3-in-1 case trimming/chamfering tool in the video above. As you can see, the tool turns very smoothly (no chatter). The actual cutting time, per case, is just a few seconds. The tool has an MSRP of $88.00, but it sells for around $65.00 to $70.00 at major vendors. Forster’s 3-in-1 Carbide cutting tool works with all existing Forster case trimmers and other hand lathes with a .490″ shaft diameter. The unit fits over the cutter shaft and secures with one set screw. The 3-in-1 cutter is available for five (5) calibers: .224, .243 (6mm), .264 (6.5mm), .284 (7mm), and .308.
