Drill and Tap Tool - Thread Tapping & Through Hole App Reviews

A very useful and efficient tool.

This is exactly what I have been looking for. So helpful!

What is a default for % is it 0 or 65%

Handy app to always have on hand!

Thru hole selection is done by changing depth of threads to zero percent. Doesnt give thru-hole with NPT threads - the only reason I bought this!

I am a Mechanical Engineer Technician Love the App. This is a very use full tool a must have App. Best Drill & Tap App.

This is a "must have" app for anyone that works with threaded hardware. It would be nice to have pipe sizes and threads.

Drill tap chart does not actually tell you what size drill to use, you have to rotate the wheel and decide what percentage of thread depth you want. If I knew that I wouldnt need the chart.

You should add Heli-coil sizes. This app will save me walking over to the wall chart even though I need the exercise.

My son showed me this app on his phone. This was the 1st download I did when I got my phone. I use it every day in my shop. Its a great quick reference. Saves time and footsteps. I really like this one. If you are a mechanic or machinist you should have this app.

I have been looking for an app like this for a while and here it is. I hate looking up a drill size and all I can find is a letter to reference the size. This app has cured that for me.

This is one handy app for the busy machinist I highly recommend it

Very handy to use along with a caliper. I have found it especially useful for finding the correct drill to use when I want the entire screw to fit cleanly through the hole. The ability to set thread depth is also great! Also great for correlating English and Metric sizes.

I love this app

I usually dont write any reviews but this application deserves one. It is very useful for my type of work, very simple to use and complete. Customer service is also great. They responded to my request in less than 24 hours. I surely will buy more applications from this developer.

If you are a "maker" you will find this app has everything you want to know before you cut threads.

Update is nice BUT the black/grey on grey selector wheel is really hard to read and out of place with the rest of the color scheme. Please change to a white background wheel, then it gets 5 stars. Update: Developer responded to my request very quickly - now the selector wheel is legible! - excellent app now.

Very helpful app for calculating my drill sizes for tapping in different materials. Lets me use a large percent thread depth for plastics and a lower percentage for steel etc.

I would like to see the British Association "BA" tap / drill sizes added.
