Round CNC gasket (Cord gasket) is essential in hold down applications when using a CNC Router, milling machine and CNC machining centers. This provides a vacuum seal between your parts and or the Spoil Board (MDF typically) and is intended to rise above the surface of your table/pod by roughly 1/16”.  Gasketing around the perimeter of this area of the table ensures the loss of vacuum leaks and provides maximum part hold down during your manufacturing Routing and Milling processes.
