The innovative 3-in-1 Case Mouth Cutter combines case trimming, inside deburring, and outside deburring into one fast, easy step. Long-lasting carbide blades simultaneously perform three functions to save time and improve consistency:
 
Trims the case to length.
Chamfers the inside case mouth to an angle of 14°
Chamfers the outside case mouth to an angle of 30°
 
The Cutter mounts on an Original or Power Case Trimmer. You can trim from 250 to 400 cases per hour.
 
First – and only – three-in-one cutter on the market to use high-quality blades made from U.S.-manufactured carbide. If used exclusively on brass cases, these blades should never need sharpening.
Carbide cutter blades are factory adjusted on the blade holder, ensuring precise cutting.
Installs by sliding over the Case Trimmer Cutter Shaft and secures with one set screw.
Caliber-specific Pilots included with 3-in-1 Case Mouth Cutters designed for popular cartridges.
 
TIP – For cases up to 2.20″ long, use the Base that comes with the Original Case Trimmer. For cases longer than 2.20″, use a Long Base, which can handle cases from 1.0″ to 3.30″ when used with the 3-in-1 Case Mouth Cutter.
