Rethread Tool M18 x 1.5 90mm Internal Thread Chaser

A rethread tool for cleaning up and repairing damaged M18 x 1.5 internal threads without moving straight to a more expensive replacement. The 90mm body length makes it useful where the thread sits deeper in the component and is harder to reach cleanly.

Used for thread repair on spark plug fittings, oil drain plug threads and oxygen sensor openings, this type of internal thread chaser is a practical option for garage work, workshop servicing and vehicle maintenance. It suits mechanics, home users and anyone dealing with worn or damaged threads that can hold up a repair job. When a fixing point has started to bind, cross-thread or wear out, having the right thread repair tool close to hand can help get the job moving again.

Handling is made simpler by the eccentric function, while the centering shaft helps guide the tool into place during use. The conical mounting shaft is included for thread repair sleeves, and the external hexagon drive together with the knurled knob gives you more control when access is awkward. With its M18 x 1.5 sizing and 90mm length, it is suited to common repair work on compatible fittings and is useful to keep nearby for regular maintenance jobs where damaged threads can quickly slow things down.
