Comments on Drill Bit Charts Pro for Android

★★★★★ A Google user · Dec 13, 2017
First app I've paid for. I do a lot of woodworking and this is very handy. Any chance you can add a feature in calculators to get volume of a cylinder and cone. That is useful in calculating board feet of a log. 1 board foot is 12 x 12 x 1
★★★★★ A Google user · Sep 4, 2014
Awesome App!!! As a mechanical engineer who is constantly specifying drilled & tapped holes, this app is right up my alley. Very nice layout and well organized. One suggestion at this point is to continue to add larger drill & tap sizes to the database. Also suggest adding tap specifications in-line to the applicable drill sizes on the drill charts.
★★★★☆ A Google user · Dec 16, 2014
Not a bad start, but still needs more. Would be nice to have the min and max sizes for each tap in their respective classes, 1b, 2b and 3b. Also, form tap sizes would greatly be appreciated. Look forward to any future mods.
