Вот как ПРОСВЕРЛИТЬ КАЛЕНУЮ СТАЛЬ сверлом по стеклу и керамике!

I show drilling holes in hardened steel using the example of a file with a drill for ceramics and glass. I have already shown how to drill a file in the tail section, stainless steel, a bearing with the same drill, and now I show how you can drill a file in the middle, right along the notch. This bit is great for hardened metal and will easily drill through tool steel. If you are still thinking about how to drill high speed steel, then watch the video and this option will probably help you cope with the task. Although this is not a tool steel drill, it will allow you to drill hardened steel at home or drill chrome vanadium steel without problems. Surprisingly, for a conventional ceramic tile drill, drilling hardened steel is not a problem at all. See for yourself.
