While not Machinery Handbook in an app this is always in the pocket not on a shelf                     Very Handy ApHapNot

This app puts at my fingers all the data I could ever need in the machine shop when tapping time comes around Very detailed and accurate                     Awesome Gilberto Diaz

Excellent Reference                     Drill Tap Brint6

I am a hobbyist machinist I am always using Drill Calc for looking up drill sizes when I am threading One feature I would appreciate is an all encompassing decimal lookup chart This single chart would contain fractional lettered numbered and metric drill sizes I also would find it helpful if you supplied the data for doing external threading                 Good but could be better Billw37

This is great all the Inch Metric and Pipe Information in one app We deal with both english and metric taps at the machine shop I work for so this makes it a very handy app                     V 2 0 works great w Pipe Thd data W8WCA

Functionality of app is great Good clean layout I agree that pipe theads would be a great addition as well as fine threads for metric taps Clearance drills counterbores and reamer drill sizes would also be a welcomed upgrade I would pay extra for those options even Keep up the good work                 Works well Dieguy

It is a plain ol drill chart and it works just fine Thanks Would like to have pipe threads too though                 Works fine TOCC

As far as I can tell does not have though hole measurements which would be easy to add to each bolt size and very useful                 Good needs though hole measurements bavetta

Great tool for any tool and die maker                     Can t live without it Robert machine shop
