Drill Bit Charts

Drill Bit Charts


This is a very simple free app with charts for drill bits sizes in fractional inches, metric, US number, and US letter sizes. It scales to larger screens on 7" and 10" tablets for easy readability.

12/1/2013 - Added a Tap Drills for U.S. Sizes chart with drill sizes for 100%, 75%, and 50% threads as well as clearance sizes.

6/12/2014 - Added a Tap Drills for Metric Sizes chart with drill sizes for 75%, and 50% threads as well as clearance sizes. Added a welcome screen to show new features.

6/22/2014 - Added a button to upgrade to Drill Bit Charts Pro which is available for the minimum paid fee It includes a handy Unit Converter and will be getting new features like a newly added Wood Screws chart.

Please feel free to rate, review, and comment on the app. It will continue to get enhancements and new features. Please tell your friends and colleagues about it.

This app is part of my RC Calculators paid app for R/C modelers. I broke it out into a separate app because I found it very useful and wanted to make the drill charts free. There is now a version called RC Calculators Free Edition. It has a Unit Converter, Engine size calculator, Battery Voltage calculator, and other tools that even non-modelers will find useful.

Easy to use Really easy to read layout. Haven't had to use it yet, but it's already better than any that come up when using google. Definitely love the "closest to" for jumping between metric and English.

Wish for metric Everything else is spectacular. I see you were trying to release in April. Just awaiting the resultant app. Other than that, excellent!
