The RT1500 Electric Case Trimmer is designed to handle the heaviest trimming jobs, including converting 223 Remington into 300 AAC Blackout. The RT1500 makes short work out of trimming large quantities of brass. The RT 1500 trim die is used just like a standard size die. The big difference is that while you are pushing the case into the die to size it, a 1/4 horsepower electric motor driving a carbide cutter is trimming the case to length. Chips are drawn off through a vacuum manifold that clamps to the outside of the special size/trim die. (Vacuum cleaner and hose not included.) Outside diameter of manifold is 1.250" where the vacuum hose connects. The RT1500 is equipped with a quick-disconnect power cord; and it can be used on any standard reloader, single stage or progressive. Available only in 110 volt / 60 Hz. NOTE: Toolhead and Size/trim dies are sold separately. Case lube must be used to size and trim brass.
