Drill Calc Reviews

Drill Tap

Excellent Reference...

~ By Brint6

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.

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.

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
