It doesn't matter what brand you buy, they all work in a similar fashion.

Carbide Tip Glass and Tile Cutting Drill Bit Sets are cheaper to purchase than Diamond tipped circular types.

To be honest all you have to be is patient (after a few mistakes, running water is not a bad idea if you can manage it) otherwise pay attention to the glass or tile you are intending to cut into and where you intend to drill.  Try to see if there is cleave point ( on bottles its obvious)  it will likely crack all the way through

Carbide tip drill bits do not walk on tile so easily, but on smooth glass like a wine bottle for instance, the possibility is much higher.  There is a suggestion to use some thing like masking tape, and I can agree with that, as it does work.

Do not force the tip with too much pressure at all times, push and pull...then clean.

Do not use high speed on the drill! If you have the option for slow speed on a drill pick it.

Often clean the area with water.  Keep the water temp cool and keep the area similar in temps or it will crack.

To prevent cracks in the surrounding areas, especially on thin material, start small drill tips and grow the bit larger one at a time.

When your done making your hole, a quick spritz of wd-40 on the drill tips once; will give you a long time life until they become useless.  How do you know?   It takes forever to make a hole!
