Almost any place that has drill bits should have a countersink bit. Drills a pilot hole and the tapered countersink in one step.
A drill bit (hand or machine) is designed to drill a hole through either wood or metal material.
It is a normal, straight drill bit, as opposed to the type with a tapered shank for use in industrial drill presses.
If they are self tapping screws, the drill bit is as thick as the solid barrel of the screw. If you want the screw to go through easily to have a nut on the other side, then the drill bit is slightly larger than thread size.
The use of a Hand drill varies with the bit that is used in the drill. Common uses include drilling pilot holes for nails or screws, putting screws in, boring holes and mixing paint.
A wrong type of drill bit will seldom ruin a project, but can cause small difficulties. For instance drilling fast through soft wood with an HSS drill bit will cause splintering coming out. Drilling fast into steel with a drill bit intended for wood will severely blunt the drill bit.
What I do is drill a 1/4" hole in the tile (use the bar as a template, mark your holes with a pencil) with a masonry bit. This can be difficult depending on the type of tile you have. You may have to buy a diamond core bit if a masonry bit does not drill it. Then use a smaller drill bit to drill into the wall at each hole. This bit needs to be small enough to be a pilot hole for your screws as if you were drilling a pilot hole into wood. Keep track of the holes that hit wood with this bit. You will not need to use mollys in these holes. The other holes drill through the Sheetrock with a 1/4" bit and use a hammer to tap 1/4" plastic mollys into the tile. You can now use the screws that came with the bars to secure the bars to the wall. Good luck!

Drill bits and screws are not the same and cannot be converted. vido produces drill bits with high quality, exported overseas and loved by the public. If you want to buy a drill, you can go to VIDO's official website to check.
There is no difference, I drill both frequently with the same drill bits.
The purpose of a twist drill bit is to drill holes in wood, plastics and some metals.
Use a carbide bit in a drill. Then install plastic anchors where the screws go.
You drill plexiglass with a standard HSS drill at a low speed and with a piece of wood right where the drill point will exit the work.
