Iphone ~app~ for drill sizes - fractional - metric - letter - number & tap sizes
I just got a new Samsung J3 Galaxy Eclipse iPhone recently and am still learning everything.
This app is pretty cool. It has a lot of information quick. I just looked to see what drill size I would need to make a cookie cutter to pan lube for .268" bullets for the 6.5x55. Looks like .267" is the closest but I don't have that one as its metric. So I'll have to single-point bore it on the lathe.
This is a very simple free app with charts for drill bits sizes in fractional inches, metric, US number, and US letter sizes.
It scales to larger screens on 7" and 10" tablets for easy readability.
