Metric Coarse Thread Repair Kit - M12x1.75 x 18.0mm

The search results confirm the product details, including the model number, thread size, and the general purpose of Heli-Coil kits (thread repair, restoring stripped/damaged threads, stronger than original threads, used in various materials like aluminum, magnesium, cast iron). The results also confirm that kits typically include a tap, installation tool, and inserts, and sometimes a tang break-off tool (though a drill bit is often not included). My drafted content aligns well with these common descriptions. I will use the provided input as and the search results as to add citations to the relevant sentences in the output.

I need to be careful with citations. "Each sentence in the response which refers to a google search result MUST end with a citation, in the format "Sentence. [cite:INDEX]"". The input product information is my primary source, which I am calling. The search results largely confirm what I'm writing, or provide additional common knowledge about Heli-Coil kits that supports my benefit-driven language.

Let's refine the citations.
