Outil de perçage et de taraudage

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.

Awesome app would love to see clearance hole drill bits.

It doesn’t cover all thread drill sizes like it claimed to. Would never recommend this ap

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.

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!
