Drill sizes
Potchkins

Awesome app I needed the the decimal to fractions for metal thickness and such when using a micrometer to get common fractions not ( .160 = 4/25 ) And now I got these other tables to use too.


Simple and to the point!

I needed a reference to double check my drill sizes and decimal equivalent. Works for me! On the next update I would like see a reference for tap drill sizes! Look forward to it. This has become on of the most used apps on my phone!


Great app

Drill chart

As a metal fabricator I have to say this a handy app. Especially when working in the field away from my printed chart. I agree with another reviewer that a drill/tap add on would be great! Worth the buck I spent.

Great little quick reference tool. Saves time having to track down a printed version. I agree with others that a tap size reference would be awesome as well.


Good app

I got this thinking that I bet I wasted my money, but after messing with the app I think it's grate. There is not a lot to the app but it gets the job done.


Very handy app

Simple, easy to use, very handy reference tool. Don't lose this as easily as my old reference card!


Does what ir says very well.

I like the various displays given, and especially liked the "All sizes" list that allows me to easily choose a drill size nearest what I want. One thing that could be added as a nice feature would be a drill size chart for tapping threads. A. very nice app worth the cost.

This will be well worth a buck the first time you have an empty slot in the drawer and you need to get as close as you can to that size. Now I won't have to hold up bits and squint to compare. I work the night shift at a forging shop and we have to fix or build whatever breaks. Now. There's no waiting for tomorrow to get an H bit or whatever from the supplier. Yeah, this'll be handy.

Does what I want.

Very convenient. This is exactly what I was looking for to add to my other conversion Apps. English, Metric, Fractional & Decimal.
