A system for replacing a heater conduit of an LNG tank, the system comprising:

• a rotary tool;
• and
• a tool head coupled to the rotary tool, the tool head comprising:
• a first cutting member having a plurality of teeth disposed about a circumference of an end, the first cutting member having a first hollow interior portion, wherein the first cutting member is sized to be received by the heater conduit;
• a body having an end coupled to the first cutting member opposite the plurality of teeth, the body having a second hollow interior portion, the second hollow interior portion being contiguous with the first hollow interior portion, the body having an enclosed second end opposite the first cutting member, wherein the first cutting member is sized to be received by the heater conduit;
• a grinder/cutter member operably coupled to the second end within the second hollow interior portion;
• and
• a solid coupler attached between the body and the rotary tool.

A method of replacing a heater element in a LNG tank, the method comprising:

• removing a portion of the heater element from an end of a conduit in a LNG tank facility;
• coupling a tool head to a rotary tool, the tool head having a diameter to fit within the conduit, the tool head having a first cutting member, a body and a grinding/cutting member, the first cutting member having a plurality of teeth disposed about a circumference of an end, the first cutting member having a first hollow interior portion, the body having an end coupled to the first cutting member opposite the plurality of teeth, the body having a second hollow interior portion, the second hollow interior portion being contiguous with the first hollow interior portion, the body having an enclosed second end opposite the first cutting member, and a grinder/cutter member operably coupled to the second end within the second hollow interior portion;
• inserting the tool head into the conduit;
• rotating the tool head with the rotary tool and moving the tool head along a length of the conduit;
• cutting, with the first cutting member, a first portion of the heater element within the conduit;
• and
• cutting the first portion into smaller portions with the grinder/cutter member after the first portion is cut within the conduit.
