Very useful tool
Used frequently & is easy to use
Disappointed
You should advise the sizes of the threads covered.
First time I used app found it did not cover the tapping size I was after 1 1/8” unf
Maximum size covered is 1” unf

Best drill and tap app!!!
I’m a machinist and industrial mechanic and use this app on a daily basis, it’s so great to have all this info with me in my pocket at all times! Highly recommend this app!!!
Stopped working, please fix!
I’ve been using this app for several years, but it stopped working, please fix it.
Great app won’t open
App is great but will not open on any devices. PLEASE FIX
Drill tap tool
This app does not work would not recommend
Good app, but will not start up
Love this app, but since the update, it will not even open. please fix this problem because I love your app

Handy app
I use this app all the time, but all of a sudden it stopped working
Clearance hole
It doesn’t appear to have clearance hole dimensions.
Response from developer
Hi there, to find clearance hole dimensions, scroll the Depth of thread wheel down passed 0%, into the negative. You can choose your clearance accurately between 0% and -20%.
Awesome app
Awesome app would love to see clearance hole drill bits.
Response from developer
Hi there, clearance drill bits can be found by scrolling the 'Depth of thread' wheel down passed 0%, into the negative. You can choose your clearance accurately between 0% and -20%, and find the nearest available drill bit to achieve that.
Horrible app
It doesn’t cover all thread drill sizes like it claimed to. Would never recommend this ap
Indispensable App
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.

Best tap drill app
I use this app daily when setting up new jobs and converting older jobs from cut tap to form tap sizes. Often multiple times per job and per day.
Having tried many machinists related apps, I find the information in this one very well presented and accurate. The ability to adjust tap hole size for difficult materials or deep threads and know what percentage of thread engagement should be created if the tools cut properly is very nice. Easy to play "what if."
Tap charts usually give drill sizes based on 65 or 75 percent engagement. When a form tap doesn't meet minor diameter requirements, using this app can help quickly determine if a smaller drill will be risky by showing what percentage thread the new hole size should generate.
Sometimes drills don't drill to size for various reasons, tools wear, and materials can be difficult. When troubleshooting I find myself pulling up this app to verify drill size and then check the drill being used and resulting hole diameter.
From a long time user of this app,
It's easy, accurate, and far more useful than a simple tap chart.
Thank you for a wonderful tool and please keep it future proof.

Needs better thru hole options
Thru hole selection is done by changing depth of threads to zero percent. Doesn't give thru-hole with NPT threads - the only reason I bought this!
Hobbyist
Simple to use for an hobbyist like me. Forget printed charts etc. this is all I will ever need and a lot more! It makes it very easy to find suitable drill size! Use it all the time and very happy with it.
Tool maker
Exactly what I was looking for. I would recommend this app.
Very good
I would like to see the British Association "BA" tap / drill sizes added.
More than just a drill chart
Very helpful app for calculating my drill sizes for tapping in different materials. Let's me use a large percent thread depth for plastics and a lower percentage for steel etc.
