You don't need a drill bit for anything on drywall.
A regular HSS drill bit will easily cope with masonite.
I use a brad tipped drill on oak and other hardwoods.
To use a sheetrock drill effectively and safely, follow these best practices: Wear appropriate safety gear, such as goggles and gloves. Use the correct drill bit size for the job. Start drilling at a slow speed to prevent damage to the sheetrock. Hold the drill steady and apply gentle pressure to avoid overdrilling. Avoid drilling near electrical wires or plumbing. Clean up any dust or debris after drilling to prevent accidents.
For drilling into concrete, use a masonry drill bit with a carbide tip. This type of drill bit is specifically designed to handle the hardness of concrete and provide efficient drilling.
For drilling into metal, it is recommended to use a high-speed steel (HSS) drill bit. HSS drill bits are designed to withstand the hardness of metal and provide efficient drilling performance.
Use a standard HSS drill bit, but slow down rotation to about 500 rpm.
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!
You need a diamond tipped drill bit to drill glass or tile.
For hanging hooks, the best type of drill bit to use is a masonry drill bit.
For drilling through sheet metal, you should use a high-speed steel (HSS) drill bit. These drill bits are designed to effectively cut through metal and are more durable than standard drill bits.
I use only a framing square, a sharp knife, a drill and two spatulas.
For drilling into metal, you should use a cobalt drill bit.
