Whether you use Metric taps and drills, US Standard taps and inch drills, or any combination of size types, this app has the answers. No typing required; just tap your thread type and spin the dials to find the correct size of drill for your thread tapping operation.
The interface allows for selection of the following variables to calculate your required drill size:
• Thread Type,
• Tap Size,
• Percentage Depth of Thread,
• Through Hole Clearance,
• Cutting or Forming Operation
The closest drill bits are given in Metric, Fractional Inch, and US No. / Letter sizes, making this the perfect tool for those using a mix of tap and drill types.
The app ensures complete control and accuracy of your operations by recalculating the actual percentage-depth-of-thread and through-hole clearance for each closest drill bit size.
Thread types include:
• US Standard UNC, UNF, UNEF
• ISO Metric coarse, fine
• National Pipe Thread - Tapered (NPT)
• National Pipe Thread - Straight (NPS/NPP)
• British Pipe Standard Thread - BSP (Parallel - G)
• British Pipe Standard Tapered Thread - BSPT (Parallel - R / Rp)
A helpful reference tool for engineers, machinists, trades-men, students, tool makers, DIYers, fitters and turners, and fabricators, etc.

Best Drill & Tap Chart App

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

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 wouldn't need the chart.
Good app

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

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. It's 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.
Great 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.
Very Useful!

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.
