As far as the thick metal drill screw for 50 cents

Screws with a press washer and drill at the end are used to build all sorts of profile systems of the thin-walled metal, but are limited to whether they can be only a thin metal? For the experiment, the thickness of the prepared decent an aluminum disc and a steel area, with a wall thickness of about 3 mm. Let's see if I can go through them?

First, we select the most suitable fasteners. As long screw is more likely to pop up and go shake, choose a shortened version pressshayboy with the screw - 16 mm. It is important that it is firmly sat on the bit, as any normal play will not work.

Aluminum was able to pass only for 6-7 seconds. More time spent on pulling the screw out of the hole. Aluminum wall thickness somewhere 3 mm. It is expected that normal drill, but so fast - no. We do not rest on our laurels and the same self-tapping drill rolling steel corner 30x30 mm.

And then it went well and the hole was ready 10-12 seconds. Somehow it was even a little hurt by the corner, a piece of iron in fact much stronger than aluminum. But not wanting to rest on our laurels, I have decided to complicate the task and drill more thick metal.

Since the thicker wall is nothing at hand was not, put two corners one by one and took to drill through them without stopping. And screws used the same again!

When re-entering the top corner succumbed almost without problems, but second clamped drill the screw at the exit from the hole, and it broke off from him, stuck in the corner tightly.

Despite the fact that up to double the positive outcome was quite a bit, it is obvious that 3-5 mm thick metal this kid is quite "progryzet", especially if they drill only one hole, not a few, as in this experiment. That's the story. Waiting for your evaluation!
