Key Features You Should Consider to Get Best

So, drill bits for porcelain tiles are like thousands of types available in the market. But do you know how to get the best drill bits for porcelain tiles? You could just learn the hard way by buying a number of them before knowing what went wrong OR we could just tell you exactly what to look for in drill bits. Let’s discuss the things to consider before rushing to the market:

Bit type

There are two types of bits, the first one of course, diamond bits and the second one is carbide tips.

The carbide tips are made for industrial works mainly as they tend be strong and can drill faster. However, they are more suitable for hard surfaces and with very less pressure. But you must be very careful with these type of drill bits as they tend to slip easily and fracture the surface.

The diamond bits are also very strong as diamond is the toughest object in the world. These types of drill bits are easy to handle and more suitable for DIYs. They give out larger holes with no risk of fracture whatsoever.

Nonetheless, both types of drill bits are strong and durable and works just fine on porcelain tiles.

Tips

There are lots of different tips seen on the drill bits and they serve some specific purpose. There are tips that are suitable for taking the core out and keeping it, there are also the spearheaded drill bits and there are tips with self-feed.

The thing you need is a high-quality tip. Tungsten carbide tips are usually the best, but diamond tips are good as well. It’s always better to buy a drill bit self-feed system, so while wet drilling you won’t worry about wetting your surface yourself.

There are also blunt tip drill bits. Now, before you say anything, yes, they are also needed. These types of tips are used for decorating tiles. The core type of drill bits are used for creating larger holes and get works done faster.

Number and size

There are different sizes of drill bits depending on how large you want you holes to be. The most common sizes are 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 1/2″, 5/8″ and 3/4″. Sometimes they come as a set sometimes they are sold separately. And as far as the numbers go, it’s better to be safe than sorry. Sometimes a single drill bit is durable enough to drill a tile or even a couple of tiles. Sometimes, people get stuck with a bad batch and the bits tend to wear off. So, it’s always better to buy a spare.

Here are a few tips for you to drill your porcelain tile:

  • Always lubricate the surface and your drill bits to keep them from overheating.
  • Keep your patience while drilling and make sure to keep a constant pressure through the drilling.
  • With diamond tips, start drilling at an angle then once you are in you can go back to the perpendicular direction.
  • Wear safety goggles (like these) while drilling
