First, start by making a pilot hole with a small drill bit. The drill may want to walk off the round face of the pipe but with skill you can hold it in place or you can make a small flat spot with a file. Once your small pilot hole is drilled then move up to the drill size you need.

Drilling Holes
What you have is called pipe. Looks like either galvanized pipe or black iron pipe.
Make sure you use a bit for drilling metal. Your bit assortment includes masonry and wood bits.

You can use the drill bits shown in your picture. The silver group in the center are masonry bits, do not use them. The group on the left and right can be used. I would start with a 3 or 4 mm bit then enlarge the hole with a 6mm.

I tried with both the left and right ones. U can see the tip of no 5 bit on the left of masonry bits is very sharp and pointed while the 6 and 8 no bits tip got blunted. That is due to my trying on that iron pipe. Also the 2nd bit on the right ones is broken and reason.... Yes you guess it right.. So please help me. I know that I don't have right bits.

Small diameter bits are easy to break, even more so if the piece being drilled or the drill isn't stable. Doesn't take much wobbling to break a small bit. I'm partial to colbalt bits. They drill steel better than the standard high speed bit.

Get twist drill bits intended for drilling metals. Its tip will look like the bit in the middle. What type or brand will depend on how many holes you need to drill. If just doing a couple than almost any will work. If you want them to stay sharper longer you can look for cobalt, Ti or black oxide coated...
