Overview of Drill Bits for Ceramic and Porcelain Tile
There are many types of specialized drill bits available on the market, such as drill bits for stainless steel, metal drill bits, drill bits for glass, masonry, etc. So before you choose the best drill bits for tile, you need to consider the types of tiles you’ll be drilling into. There are three main types of tile surfaces.
Types of Tile
Main Types of Tile Surfaces: Ceramic, Porcelain and Stone
Ceramic tiles are one of the most popular types of tiles used around the world. Ceramic tiles are made of clay materials.
Ceramic tiles are fired in a kiln at a lower temperature than porcelain tiles, this makes them a little softer, a little more porous (they let a little more water through), and they aren’t quite as dense as porcelain tiles. They are also a little lighter weight, which makes it easier to transport and install them.
Ceramic tiles can be glazed (a mirrored or polished finish) and an unglazed, more natural appearance. Ceramic tiles are often used for wall cladding and for flooring. Because ceramic tiles are lighter weight than porcelain, they are often a better choice for using on walls.
Porcelain tile is denser than ceramic tile is. Therefore, this type of tile is a bit more expensive.
Porcelain tiles are ideal for using on floors because they stand up to heavy foot traffic. Just make sure the floor is strong enough to support the weight of the porcelain tiles as well as people, furniture and any machinery that will be on it.
Stone tiles are made from different types of stone. They can be marble, granite, slate, limestone and more. Stone tiles can be ground, polished or left with a natural finish, especially on slate tiles.
Stone has its own kind of warmth and beauty and comes in a wide range of colors. Some stones are stronger than others. Marble is a soft stone, granite is the hardest, so remember this if you are choosing stone tiles for flooring. If you are going to drill a stone tile, then you will need to be patient, because it will not be easy.
Buying Guide: Best Drill Bit for Tiles
If you choose the right drill bit, you will definitely get a clean, neat hole in the tile. Make sure the bit is designed for drilling into tile, and check how deep the bit can go. Many drill bits are designed for only ½” of drilling depth. Some of the big bits can handle a drilling depth of 1 7/8″.
Only Buy A High Quality Tip
To do this, look for a drill bit with a tungsten carbide tip or a diamond tip.
If you want your drilling to be accurate, make sure the drill bit tip is designed to prevent walking as this will mar the finish on the tiles.
Also, one of the common problems is the drill bit overheating due to the friction of drilling such hard substances as ceramic, porcelain and stone. I recommend that you moisten the tip with water, or use plumber’s putty to build a dam around the drill hole area and fill it with water. This will keep the drill bit cooler while you are drilling. Also, don’t dry to drill too fast. Slow down!
Number of Drill Bits
I often hear the question, “how many drill bits do I need to drill a tile?” It all depends on how many holes you are going to drill, and whether you go slowly and keep your drill bit cool, or go fast and burn out your bit by overheating it.
One drill bit will be enough to drill several holes of the same diameter if you use water and drill at a moderate speed.
If you plan to make holes of different diameters, you will need a set of drill bits. Sets come in different sizes, from 4 bits to 16 bits.
Drill Bit Sizes
There are different sizes of drill bits. Most often in retail stores or on the Internet, you can find drills in the following sizes: 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 1/2″, 5/8″ and 3/4″. There are also metric sizes, which are listed in millimeters (mm).
All common drill bit sizes can be bought as individual bits and in sets. The really large drill bits are only sold individually.
How to Drill Ceramic and Porcelain Tiles
And now we turn to the most interesting how to drill tiles. Honestly, this is not easy, and therefore I will describe the whole process in a few steps.
Do You Know Your Tiles?
Pay attention to the type of tile you are going to drill. You need this information in to use the characteristics of the tile for better drilling.
For example, your kitchen floor is made of stoneware tiles.
We already know that this type of tile is dense. That is why the drilling of such tiles requires more time to work and to prepare for it. It the tile is stoneware and dense, then any drill will not work. You need a special drill bit that will make a neat hole in such a dense tile. That is why it is important to know the type of tile before drilling a hole.
What Kind Of Drill Are You Going To Use?
Ok, let’s imagine we figured out the type of tile. Now we need to clarify which drill to use for an excellent drilling result. You can immediately put the old drills away because worn drills will ruin the tile.
Keep in mind: in such an important matter you only need to use new drill bits that will outperform the old ones in efficiency. The new drill will not damage the tile surface.
Forget about ordinary drill bits, because such bits will not be strong enough and will not penetrate a hard surface.
The best way is to buy a new diamond or carbide stone drill bits. Why?
The point is that diamond drill bits ideally pass through even stone tiles. And yes, you can use these drills in the future. It is ideal for porcelain and stone. Carbide tipped drill bits cut through ceramic tiles.
Measure 7 Times And Drill Once!
Often there is a problem with drilling: the drills slide along the tile surface. In this case, it is almost impossible to keep the drill in place. It is fraught with the fact that the tile surface will be damaged.
In order to avoid such problems, it will be good for you to measure the distance between future holes. Take the duct tape and use it around the place where you place the hole.
Be sure to measure the area of drilling and place the masking tape on this place. Measure the area again after using masking tape.
The purpose of this trick is to ensure perfect adhesion to the tile surface. It will help you to grab the drill precisely in the place where you want to get a hole.
And What If You Are Going To Make Some Holes?
In such cases, I do this: I make a template from a wooden block with the marking of drill bits. It is simple: I make a hole in a wooden block as I want the holes to be placed on the tile.
I place this wooden block above the tile and boldly make holes.
We Start Drilling!
Did you perform the previous step? If yes, then it is time to move on to the most important thing – that is drilling.
Keep in mind – you cannot rush in any case. Drilling tiles is a difficult process, and any rush can ruin everything.
Be patient and do not hurry, then start drilling holes. And yes, keep low speed. Make holes very slowly, because you need to penetrate a hard surface. If you hurry, then you have every chance to damage the tile surface.
Stop Your Drill Bit From Walking!
Often there is a problem with drilling: the drills slide along the tile surface. In this case, it is almost impossible to keep the drill in place. This is a problem because the tile surface will be damaged.
In order to avoid such problems, put some duct tape over the place where you will drill the hole. Clearly mark the center of the hold on the duct tape, using a marker or soft carpenter’s pencil. Or, better yet, buy a drill bit that is designed not to walk when drilling tile.
Cool Your Drill Bits!
I have already said that your drill bit will last longer if you lubricate the bit with water before you begin and keep the bit wet while you’re drilling. Often I use a wet sponge with which I lubricate the drill for cooling to avoid overheating of the drill. You can put this sponge under the drill so that it is always cool.
It is also a good idea to stop for a while and let the drill bit cool off in water. And, as we mentioned earlier, don’t try to drill too fast.
What Do You Need To Know When Drilling Porcelain?
Use diamond-tipped tile bits. And even if you’re using the best drill bit for drilling porcelain tiles, don’t let the bit overheat. Be sure to start drilling slowly, constantly splashing the drilling area with water.
Never use a lot of pressure or high speed. Generally, the rules for drilling porcelain are the same as the rules for drilling stone and ceramic tiles.
So now you know how to drill different types of tiles.
The success of drilling in tough materials such as ceramic tiles or porcelain tile depends on several factors: patience, a slow drill speed, keeping the drill bit wet, and using a drill bit designed for drilling tile.
So, now you’re ready to start drilling, check our reviews to find the best drill bit set for ceramic tile, the best drill bit for porcelain tile, the best diamond drill bit for ceramic or porcelain tile, and get drilling!
