Not I.

Don't suppose you've got an M6 tap with a 1mm thread pitch, though?  ;D

I'm only kidding mate, I will most likely go buy one, given the V low cost against postage.

Any ideas what size drillbit to use, if I want to thread out to this size?

Cheers

I have a tap set if you want to borrow - but quite low quality (ebay special)

5mm for an M6.

The general rule of thumb is the drill needs to be approx 0.83 (5/6ths) x tap size.

I.e.

M3 = 2.5
M4 = 3.3
M5 = 4.2
M6 = 5.0
M8 = 6.8
M10 = 8.5
M12 = 10.2

Cheers Mark, I will go out and get a 5mm drillbit and the M6 tap later, for my LPG injectors :y

The drill bit size is determined by the thread pitch. Subtract one from the other to give the size (then round it to 1 decimal place).

eg...
M6x1 = 6-1 which is 5mm

M8x1.25 = 8-1.25 which is 6.75mm nearest drill bit being 6.8mm
