The first thing that strikes you when you pick up the Giraud Tri Way Case Trimmer is how well it is constructed. It is heavy, solid and very well machined. Manufactured by Giraud Tool Company in the United States for high volume shooters, specifically to deal with the issue of rapid, repeatable, and accurate case trimming. The Tri Way is designed to be powered by an external electric motor such as a drill press, milling machine, lathe or even a portable drill. Trimming brass does not require high RPM tooling. In one operation, the Tri Way trims, chamfers and deburrs a case in seconds.
The Giraud Tri Way Trimmer indexes from the case shoulder, and your brass needs to be consistent to achieve accurate results. Most users will re-size before they trim, which sets their brass up perfectly for trimming with this tool.
Please watch our video demonstration showing a couple of different ways to use the tool here, where results were +/- 0.001 at worst. Most cases were perfect.
Each Giraud Tri Way Trimmer is adjusted at factory. A factory test case is not supplied with overseas shipments from Giraud. It is strongly recommended that you size and trim a ‘reference’ case and keep it somewhere safe before you disassemble and reassemble the tool to factory specifications. Should you wish to customize the case length you can easily adjust the tool to achieve the desired results. The Giraud Carbide blade is supplied with the trimmer. This blade is set to chamfer the inside case mouth at 15 degrees and the outside case mouth at 45 degrees to facilitate bullet seating.
Robustly constructed with smooth high quality bearings, this tool is a great solution to your case trimming problem. Product support is available from the Bisley V Shop or Giraud Tool Company. The supplied carbide blade has 3 cutting surfaces and can be rotated when a surface dulls. Blade life expectancy is between 25,000 and 100,000 cases, but can be replaced as needed.
Well written technical instructions are provided. The tool can be used horizontally or vertically as required. This particular tool will work with .308 Winchester and derivatives such as the .243 Winchester, .260 Remington, and 7mm-08.
Other calibres are available. We stock this tool in Giraud Tri Way Trimmer 223 Remington. Please contact us to order a tool in your calibre.

Really impressed with the quality and finish of this trimmer, I have mine in a drill press and it quick and easy to use just one step to trim, deburr and chamfer. It comes preset so no need to adjust mine was trimming to 2” exact. The finish of the cases is superb and very uniform and smooth so no razor sharp edges lol
