Also has the M8x1.0 and M8x1.25 tap and dies for chasing the threads on the cylinder head studs.

Don't buy cheap taps and dies...there's a reason why they're cheap! Yes, they're hard steel but VERY, VERY brittle.

Imagine tapping a hole and the tap snaps off. You can't just drill out the tap because the tap is harder than the surrounding metal and your drill will go off center and really screw things up. Whatever money you saved buying cheap taps will be spent buying the tool you'll need to extract it. Cheap dies go dull fast if they don't crack in half first.
