The RCBS Rotary Case Trimmer Collet #1 (RCBS part no. 9371) secures a case in place the way a draw collet holds work on a lathe, so it stays put while the RCBS Rotary Case Trimmer brings it down to length. It is built to work only with the RCBS Rotary Case Trimmer and Rotary Case Trimmer 2, not RCBS’s other trimmer designs, so it is a direct replacement or add-on part for reloaders who already run one of those two trimmers. Find it filed with our other reloading equipment selection.
