Pneumatic Decapping System


The Lithium Machining Pneumatic Decapping System is a must-have in commercial manufacturing. So many decapping dies compete for having the hardest pin, bragging about how it punches through berdans and small flash holes. This only creates problems by pushing the excess brass from your newly punched hole down into the primer pocket, causing issues while priming. While our pin is incredibly strong being made from M-2, we instead tackle the issue by absorbing the force back into the air cylinder.

The other advantage of the system is it keeps the pin up and protected inside the stem during the entire operation. This prevents it from being exposed during a machine crash. 

The Lithium Pneumatic Decapping System has been used by manufacturers for years but now includes some slight modifications. We have raised the cylinder to include clearance for the FW Arms Swage Backer Die. Lastly, we changed the design so there is no need for a return spring on the decapping pin, reducing maintenance parts and increasing reliability.

You will need a mount for the actuator. I highly suggest the one made for the Holy Moly Plunger Support Assembly.

You will also need the Toolhead if you don’t already have one.
