The Mud Viper from Rattler Tools Inc., is a powerful Surface Magnet, which allows for greater ease of operation. The magnets have been run on Casing Milling Operations and are proving to be very successful.
The image above shows that the "magnet insert" is installed into the ditch magnet housing during operation. Once the "magnet insert" is removed, the debris simply falls off.
