Drill bit sizes

[littlebeaver]

Perhaps someone can use this, I find it extremely helpful as I don't have all of these measurements memorized.... http://www.gearhob.com/eng/design/drill_eng.htm It sure helps to get the correct bit...

Thanks. That's much easier to read than the faded ones in my grandfathers old toolboxes. Used to be, I'd just ask him, even into his 80's he still remembered all that stuff. 40+ yrs as a machinist.

I know all the typical 1/16" thru 15/16" but it gets pretty precise with the sizes between...

Thumbs up!

Before I needed reading glasses to do this, someone told me to use a bit whose O.D was slightly larger than the shank of the fastener I wanted to use. (ie. not the thread dia.) Almost always works for me. I did bookmark it though. Thanks.

For those of us with an android based phone, there is an app called "drill bit charts".

Extremely useful.
