Really well done video on taps! I used to help teach in a school and saw people on CNC tapping aluminum with hand taps. Needless to say they got munched up and I had to reach why to not use hand taps! That said recently I started using forming taps in aluminum and boy could I not be happier. Taps last a long time, finish is impeccable and it takes less force in a small drill press application tapping sheet 7075 aluminum.
If you're looking to go deeper with a tap use a "bottoming tap." They are designed with 1-2 half threads at the end of the tap. A more common "plug" tap has around 4 half threads. the "pointiest" of the commonly available taps is a "taper" tap with 7-10 half threads. Many people use the taper tap to start threading a hole and then switch to a "bottoming" tap if needed.
Nice vid. I wish you can help us to select the propper tap to make threads on a short blind hole. We need to make 5/16-24NF on a part made of 12L14 steel (pretty soft) but we want to know the minimum thread depth. Knowing that valie we will design the part and make the prototypes using the tool. The hint is, we want a tap which help us to make a really short blind taped hole.
Hello! Thank you for your question. Our suggestion for you would be to use a CoroTap 300 XM with a bottoming chamfer (Chamfer E with small lead). This will give you 1.5 -2 x pitch lead only, then you can start to produce the full thread.

Hi, It’s not possible to give a recommendation without knowing the thread form and size required. M8 M10 i.e. metric / metric fine / UNC etc. Use the CoroPlus® ToolGuide (link below) and get recommendations based on your application details. www.sandvik.coromant.com/en-gb/products/Pages/toolguide.aspx Take care!
Well taps are tapered towards the front so positionally probably doesn't matter if your a hobbiest. But you should definitely chamfer before tapping if you want a nice clean entry for your screw. other wise you can get a burr that prevents proper feeding
Killer jacket dood. Tapping in the rain, are ya?
If you keep the doors open on the CNC machine you can see better. Just keep the mop handy.

Hello, do you suggest to chamfer the hole before tapping? Can it help centering the tap or is it unnecessary?
Well taps are tapered towards the front so positionally probably doesn't matter if your a hobbiest. But you should definitely chamfer before tapping if you want a nice clean entry for your screw. other wise you can get a burr that prevents proper feeding
