FAQ:

Q: How do you drill a bigger hole?

A: To drill a large diameter hole in tile: Mark the outline of the hole with an indelible marker. Use a nail set to punch a series of indentations around the perimeter of the tile. Use a 1/4″ carbide tipped masonry drill bit to drill holes through the tile at each of the indentations. Cut through the glazing between the holes with a cold chisel.

Q: How can I tell the size of a drill bit?

A: How to Size a Drill Bit Check the Shank. Typical drill bits have markings somewhere on the shank above the threads. … Calipers. Calipers are small hand-held tools. They look like a small, flat handle with two jaws at the top. … Test Hole. When you purchase a new set of bits, or identify your old ones with calipers, drill a series of holes through a thin, flat piece of metal.

Q: What is the hardest drill bit for metal?

A: Tungsten Carbide. The basis for many of the hardest drill bits is tungsten carbide. A metal that is five times stronger than steel, tungsten carbide by itself makes for a very hard drill that’s quite resistant to heat. However, it can be brittle, so only the tips of many bits are made of this metal, though it isn’t uncommon for entire drill bits to be made of it.

Q: What are carbide drill bits?

A: The carbide drill bit is the preferred slow-speed cutting tool of drilling and boring companies that specialize in masonry and rock boring. By adding a cooling fluid to the cutting edge of the tool, it can also endure high-speed use applications, including milling machine and computer-aided cutting machines.
