Glow Plug Rethreading Tool M12 x 1.25 270mm Thread Repair

A glow plug rethreading tool used for cleaning and re-cutting damaged M12 x 1.25 glow plug threads. With a 270mm length, it is suited to reaching threads set deeper into the cylinder head where access can be more awkward.

Used for engine servicing, vehicle maintenance and repair work where a damaged glow plug thread needs putting right without replacing larger parts unnecessarily. It is the sort of glow plug tool found in garages and workshops, but also useful for occasional repair jobs when working on diesel engines with recessed glow plug positions. When a thread only needs tidying or restoring, this gives a practical way to carry out thread repair work more directly.

The longer body helps when access is limited, while the centring shaft assists with keeping the tool aligned as you work. An eccentric function is included to make handling more manageable during repair, especially in tighter engine bay areas. The conical mounting shaft is intended for thread repair sleeves, and the external hexagon drive with knurled knob gives a more secure hold during use. For regular servicing and repair work, these features help make awkward glow plug thread jobs more straightforward.
