Title: Available drill sizes?
Post by: RogerClark on April 05, 2016, 03:40:37 am
I've looked around on the site, but I can't see a list of available drill sizes.

I know the PCB house will just use the drill size closest to the one in the drill file, but it would be good to know what these are likely to be

I found a list in a few places e.g.

 .020, .025, .029, .035, .040, .046, .052, .061, .067, .079, .093, .110, .125  (dia in inches)

Are these sizes preferred ?

(I ask as I have some plugs with 1.4mm pins, which I need to drill to around 1.6mm or perhaps 1.7mm and I was trying to work out the best drill size to use, to match the PCB house)
