Spark Plug Thread Chaser M14 x 1.25 270mm Deep Reach Tool

A spark plug thread chaser for cleaning and re-cutting damaged M14 x 1.25 threads where access is awkward. The 270mm long body is made to reach deep into the cylinder head, helping with spark plug thread repairs without stripping more parts than necessary.

Used for engine servicing, vehicle maintenance and workshop repair work, this tool suits garages, mechanics and DIY users dealing with worn or damaged spark plug threads. It is especially useful when the plug hole sits deep in the head and a standard thread tool does not give enough reach. For awkward access jobs, the centring shaft helps guide the tool into place more accurately while working down inside the plug opening.

The M14 x 1.25 thread size matches a common spark plug thread fitment, and the long reach helps when working on engines with limited access around the head. An eccentric function helps with handling in tighter areas, while the knurled knob gives a steadier grip during setup and use. Also fitted with an external hexagon drive and a conical mounting shaft for thread repair sleeves when required, it covers the practical features needed for thread cleaning and rethreading work. Useful for regular maintenance where damaged threads need sorting before they become a bigger repair job.
