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..

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.
