Are You Looking For The Best Drill Bits For Porcelain/Ceramic Tiles in 2019?

While porcelain tiles are mostly preferred by home owners, they are also the hardest to drill through. A newly tiled bathroom can start looking ugly in an instant if you happen to have one wrong move or one wrong slip while drilling through the tiles. Screwing into porcelain tile presents its own set of challenges because porcelain is dense, hard and much heavier than a ceramic tile. To be honest, drilling small holes in porcelain tiles could still be easier but if have to drill one for a pipe; it could very well be a Herculean task. The fact remains that porcelain tiles need proper tile bits that will efficiently drill through without breaking them. How and where to find the best drill bits for porcelain ceramic tiles? Let us find out!

Understanding Porcelain Ceramic Tiles

Porcelain ceramic tiles have a very low rate of water absorption which makes them an ideal choice for bathrooms, kitchens and showers. They are also great choices for walls and floors because they are dense and durable. The manner in which they are manufactured in a kiln makes them even more difficult to drill through without breaking the adjoining tiles. There are particular types of drill bits that are essentially made to drill through porcelain and in this article; we will help you understand the difference and the need.

Best Drill Bits For Hard Porcelain Tile

Three different types of drill bits are ideally used to drill through porcelain tile and they are listed below:

• Diamond tipped drill bits
• Tile bit
• Masonry bit

Diamond drill bit for porcelain tile is what you ideally need. You can also manage to do your task with masonry drill bits but when it is a matter of perfection, you simply cannot do without diamond tipped drill bits. Drilling through high grade of porcelain is difficult but you can trust diamond tipped bits to make their way through.

The only concern with diamond drill bits is the fact that they need cooling down. It is thus important to use water while drilling with these bits. Spraying water on to the drilling surface helps cool it down to an extent and also adds to its lifespan. Apart from this aspect, diamond drill bits will lead to precise, neat and clean holes that you might have been waiting for all this while.

How To Drill Through Porcelain?

While using diamond drill bits to drill through the perfect porcelain wall, then remembering the following steps will help you perform better.

1. The first step is to mark the centre of your hole.
2. The second step is to cover that centre with a strip of masking tape and mark the hole again. The step ensures that the bit does not slip away even when you apply pressure to it. In the worst situation, if the bit does slip, the masking tape will keep the tile safe.
3. If you are using a variable drill, it is recommended to start slowly and go slow till at least the surface is broken.
4. The fourth step is to spray the drilling surface with coolant or water.
5. The final step is to use only as much force as is required to keep the process going. It is wiser to avoid exerting too much pressure because there is always the fear of the tile cracking or splitting.

While following these steps, the most important thing to remember is to never use the hammer drill setting while starting off because you might end up cracking the tile even before you can start drilling.

Using Diamond Drill Bit For Porcelain Tile

Once the above steps are covered, the most important task at hand is to ensure that the porcelain tile does not break. The only two tricks that are required at this step are patience and accuracy. Once the diamond drill bit breaks through the tile surface, you need to use the drill at a consistent speed until the desired depth is attained.

Always ensure that the wall you are drilling does not have electrical or water cable lines running behind them. Diamond tipped drill bits are prone to overheating so frequent pausing is recommended and dipping the drill bit into water is also suggested by professional woodworkers.

Once the drilling is over and the task is nearly done, you must ensure that you decrease the speed and pressure of the drill to slowly remove the drill bit from the tile’s surface. Once this done, you might have hopefully drilled through the surface without causing damage to the adjoining surfaces.

Why are Masonry Drill Bits not as effective as diamond tipped drill bits?

There is always an option of picking the less expensive product but when you pick it up, do consider the pros and cons of your choice. When it comes to drilling through porcelain tile, using a masonry drill bit could very well be a sub-standard alternative to a tungsten carbide tip or a diamond tipped bit.

A masonry tip might work but it will not give you a neat hole. If you happen to examine a hole drilled in a porcelain tile that has been drilled by a masonry bit, you will realize how the edges and the surface around the hole are chipped. It looks untidy and fails the whole point of buying it in the first place.

At the end of day, it all comes down to deciding the amount of drilling that is required to do. If you have to drill a few holes that will have the same diameter, then a masonry drill might work but if you are a DIY enthusiast and porcelain tiles happen to you often, then a diamond tipped drill bit could be your only solution.
