Excellent! You can choose metric or SAE and it lists every screw size. You can choose the percentage of how tight you want your threads to engage, with a material guide, and it shows the actual hole size you need and the best drill bit sizes. And you can click on your screw size and it lists all possible drill bit sizes, metric, SAE and number, ordered by percentage of thread engagement so you can very easily pick the best drill bit for your tap, or the next best one! Very good app! Thank you!

Love this app, I use it quite extensively at work. I love how you can choose the percentage of thread that you like. I do wish it had smaller and bigger sizes as well as NPT, BSP, PSPP, and maybe a section for special threads and/or a calculator.
