The Gold award for Hand Tools goes to the Pro-Fit swaging tool from RectorSeal.
Pro-Fit swage bits create precise and fast swage in copper and aluminum line sets, mini-split HVAC units, and other similar applications. The spinning hex bit forms a consistent swage without splits, burrs, blemishes, or uneven edges that typically cause swage fitting connection leaks. The bits burnish swage surfaces reducing the risk of leaks. The hex bits are color-coded for easier identification.
