Yeah the recoil kit I have for this size is a special tap.

Its sized like an M12 but pitched like an M10 if that makes any sense.

Not sure if helicoil taps/parts are interchangeable with recoil.

Your welcome to borrow if you want, I live in hami-hill but work in kwinana beach if thats any help.

actually my kit is m10 x 1.5 so probably no help.
