Questions?? 2.5m Drill Bit??

^2.5mm*****
I'm currently building a TA05v2 kit and one step calls for a 2.5mm hole to be drilled..
I'm having trouble finding a drill bit for the peices that require a 2.5mm hole drilled into them.


I used this converter chart but the 2.5 designation space is left blank..
http://bobmay.astronomy.net/misc/drillchart.htm

I went to a hardware store and an employee recomended a #41 size (which is smaller than 2.5mm) and we both had no clue what that would be in the fracton form for inches.

but I know 2.5mm = .0984 inches

Does anyone know what size drill bit I need??

Thanks

Drills can be bought in fraction, number, and letter sizes. The drill he suggested is a number drill. I use them all the time because they change size in much smaller increments for situations where you may need to tweak a hole size by only a few thousandths.

I would buy a #39 and #40 drill bit. Start with the #40 and if that is too small for whatever needs to go through the hole, then use the #39. We're only talking about a couple of thousandths of an inch on either side of your target size. The nearest fractional sizes are too far off your target size in my opinion.

Thanks! I'll be picking those up in a couple hours

Thanks for the link! Besides for the conversion charts, I didn't think about looking online at all.
