Limestone is not hugely popular as a tile though it is really good if you are trying to create a rustic look. Unfortunately limestone is very porous so will need regular sealing. It isn't a tile we would recommend. These diamond-tipped drill bits are similar to regular drill bits. They are tipped with diamond chunks and are most suitable for dry drilling. These drill bits can penetrate the hardest marble surfaces in a few seconds. Tungsten carbide bits make drilling through tiles pretty easy. You do need to use these with a drill that has a slow speed so a variable speed electric drill is a must. Before drilling a hole through marble, you have to choose the right bit. These bits are easy to use with your regular drill or a hammer drill. Diamond Tipped Bit In that situation, complete the last few millimeters of the hole with a standard masonry drill bit.

If you just need to drill a few holes with the same diameter, then just buy a single drill. Most people though will need to drill different sized holes, and when that is the case, then a set of drill bits is more economical Core bits are tipped with either diamond or carbide. Core bits have a central pilot bit that holds the bit in place while the outer sections of the bit drill through marble and granite. Core bits are commonly used to make larger holes bigger than 1/2 inch. Spade Bit Before you start drilling, create a workspace that is free of people, clutter, and debris. Any clutter near your drilling surface may move once the drill is activated, which could cause your drill to slip.Travertine offers neutral tones such as sandstone. Like limestone it is also very porous so will need regular sealing. If used in small amounts in walls it can look great but is subject to staining easily. If you decide to go with these, you will need water applied to the tip throughout the drilling, and they are more expensive. That said, they work like a treat and last for a very long time. For us it all comes down to the amount of drilling that you will have to do. For most home owners that will be in the kitchen, the bathroom or the utility room.

Most marble cuttings needed for a larger home renovation use a wet tile saw. However, for smaller circular cuts in your kitchen or bathroom, you'll need a drill bit to penetrate marble. Need an extra electrical outlet or room for a power cord? Here’s how to drill through marble safely. Types of Marble Drill Bits Important: I’m using a 6mm diamond-tipped drill bit for this demonstration. Also, if you are drilling a finished marble tile surface, get a 6mm standard masonry drill bit as well. I’ll explain the reason in the drilling step. Carbide-tipped bits can be categorized as strong drill bits made from carbon and tungsten. These bits are commonly used for drilling tiles, masonry, concrete, and marble. These super-strong bits are made from a compound of tungsten and carbon. They’re commonly used in industrial applications and can cut a hole through tile, concrete, masonry, and marble. Core BitOnce you’ve drilled all the way through the marble, slowly move the drill out of the hole and away from your surface. It’s necessary to protect yourself whenever you’re doing a DIY project. Be sure to use proper protective equipment, especially when you are operating a drill. Ear protection and goggles for your eyes will help protect against any dust or debris. Porcelain tiles need a special drill bit for best results, but any of the sets we mentioned above will get the job done. Other types of tiles and hard surfaces like slate, marble and granite can be drilled through using a tungsten carbide bit, or a diamond tipped bit. You can get either honed stone or polished stone. Honed tends to be used on floors, and polished on walls or areas with a low foot fall. Slate is usually only used for great looking floors. Marble can also be used for worktops as can slate in some cases.
