Kit arrived today. Does anybody know what these bits are for (blue circle)? They are metal tubes. There are no instructions and i cant find the answer online.

If they are hollow with different outside diameters, then I would guess they are sleeves for protecting the glow plug hole, while helping to centre the drill bit.

Drill guides for drilling out centre electrode if it doesn't come out with the top.
Laser tools instructions which will tell you about it here: www.lasertools.co.uk/items/PDF/Products/5205_Instructions.pdf
I'm surprised yours didn't come with some form of instructions.
