Drill Calc App Reviews

V 2.0 works great & w/Pipe Thd data. 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.

App fail to load. I was unable to access the app after downloading it. Restarting my phone did not repair it. Money wasted.

Drill Tap. Excellent Reference...

Can't live without it. Great tool for any tool and die maker.

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

Works well. 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

Awesome. 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.

Good, needs though-hole measurements. 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, but could be better. 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.

Value for money. Great for 99% of threads metric or imperial. Metric could have a few more of the common pitches listed. A seperate group for BSP threads of both US and UK types would be great.
