Quick technical question please...
 

I'm about to google it, but if any1 has an instant answer there's a brownie point up for grabs:

What size hole do i need to drill to tap in a M10 thread?

a small one;)

About 4' 3" I reckon.....:lol:

If it's for the DD bike I suggest you ride it flat out into the side of a skip then cover it in petrol and set fire to the bugger!! Nothing left to tap, nothing left to drill.....

I should really be on helpdesk.

Nick!:o

stay away from motorways, I ask you - the M10?:puzzled:

C:P

oh dear! :(

2 tics, just shouting at AK in garridge!:D

He says: 8.8mm

HTIOH?

C

If you look in The Big Book of Predictable Replies you find exactly what was said in the first three replies...... sorry... :(

Will go and check now.....

Intraweb say 8.5mm for a standard thread and 8.8mm for a fine thread.....

Thanks AK, I just found it in a engineering forum... says between 8.5 and 8.8mm depending on material.

Tapping into alluminium so I think a wider thread would be needed so I'll start with 8.5

Give Al a brownie point anyway.

Ali... I expected nothing else!

am feeling proud of AK now - didnt need a book & called back to me ....whilst fiddling in garridge

Clever hubbie!:D

Thanks guys.
Right then, back to my new drill press :D

Don't forget to take yer posh trousers out first sonny ;)
