VARIOUS APPLICATIONS: High-speed steel (HSS) ST14x1.25 M14x1.25 (14mm thread size) suitable for damaged spark plug threads to clean and rethread spark plug ports with either a tapered seat or a gasket seal type spark plug assembly on a lawn mower, car, or other vehicle engine; Stepped tap ensures correct alignment of cutter in existing spark plug hole; Extension tools allow easy access to the bottom of the plug recess (includes plug inserts). EASY TO USE: Cut a larger threaded hole in cylinder head with tap, screw insert into head, screw plug into insert, use expander to help seat insert by tapping with a hammer; Select insert that covers as much of the plug threads as possible to avoid carbon buildup (this can make unscrewing plug from insert difficult); Use grease on flutes and any cutting tool to catch shavings, clean often, and vacuum when finished (grease not included).
