    How to use a HELI Coil tool to repair a stripped thread.

    Hi all not sure if any of you are familiar with these thread repair tools.
    Basically what Ill show is how to use it,,,, first I need to drill the thread out to a larger
    hole,, the drill is provided,, Then tap a hole to suit the new thread,,,,then screw in the new thread
    Ill do it bit by bit. These tools were very popular years ago with motor bikes
    stripping the spark plug hole.
    OK first is a view of the tool itself nothing to be scared of, its just
    a drill, tap and a tool to insert the thread and the threads themselves
    This is a permanent repair.
    Forgot to mention, what Im repairing is two stripped holes on my
    thermostat housing so I can return it to Mudski, the thread Ill repair
    is 8mm x 1.25 some call it 8mm fine
