Been using Drill Bit Charts Pro for a couple months now. It’s basically an app that has all these charts and reference info for different drill bit sizes – you know, like fractional inches, metric, that kinda thing. Pretty solid app if you’re into construction or DIY projects and need to look up the right drill bits to use.
Here’s what you can do: there’s charts for tap drill sizes, both for US and metric threads. Comes in handy when you’re trying to figure out what size pilot hole to drill. It’s got wood screw sizes too, so you know the right clearance holes. And they just added some stuff for pipe taps, which is cool. Oh, and there’s a unit converter built-in for the pro version, which is pretty useful.
Look, if you work with a lot of different fasteners and drill bits, you’ll probably find this app really helpful. It’s not perfect – the UI could be a little more polished – but overall it does the job and saves me time looking stuff up. Worth checking out.
