Drill and Tap Tool - Thread Tapping & Through Hole

Used frequently & is easy to use

I’ve been using this app pretty much since it came out and consult it regularly at work. Though I’ve been in the trade long enough to remember most tapping sizes by now, I often use it to identify threads, particularly larger metric threads. It now covers Metric, UNF/UNC and both British and American pipe threads. That covers most threads you’re likely to find these days. Though I did some repairs on a 40 year old fork truck recently, which had some BSF/BSW threads, so for completeness that would be a useful addition. But for most people, this is all you need.

This app is very useful for people in the trade and a great replacement for other charts, support is amazing I had one problem (this wasn't a problem in the end) that was explained to me within hours, great stuff a engineers must have.

This looks great although it is missing the worlds most popular pipe thread BSP. That was the reason I wanted the app in the first place. It would be great if you could add it. Can't wait for update. !

I’ve been using this app for several years, but it stopped working, please fix it.

App is great but will not open on any devices. PLEASE FIX

Was a great tool. Have iPhone 14 pro max, can’t use the app anymore. So sad!!!

Love the app, please update!

I use this app all the time, but all of a sudden it stopped working

It doesn’t appear to have clearance hole dimensions.
