drill bit sizes
 

there was a post on here some were a few weeks ago, about the difference between imperial and metric drill bit sizes for drilling out pistons, i found this little conversion chart and thought it might be of use to some people so here it is,

These are really useful - here's one I've used for a while now...

www.expotools.com have sets of small drill bits, well worth a look, carry some really good kit. i use them for all sorts of bits, i'm lucky though, they are only about ten miles away from me

Nah, they aren't ;)

Metric and imperial are never a direct replacement, they are always slightly bigger/smaller than the imperial size etc.

I got 1.2, 1.3 and 1.4mm from my LHS that does model trains and what not... 60p each.

there not if your anal enough to measure down to 0.001"and 0.0001

Or want to swap set-ups with other people...... :woot:

G

on a toy car, nether you me or anyone else would be able to tell the difference and you no it,o and the piston drill i bought of you are not exactly 0.55" any way so shhhhh :)

that should do the trick yeah?

Not exact, but it has useful increments in sizes from 0.3mm to 1.6mm
