Steps for Drilling Through Tile

Step 1: Determine the type of tile you have

There are generally three types of tiles:

  • The most prevalent type of ceramic tile you’ll find in almost all older homes and the easiest to drill through is glazed ceramic.
  • Glass tile has only been around for roughly 15 years and is mostly utilized as an accent.
  • Ceramic tile that isn’t porcelain has a similar appearance but is tougher.

Step 2: Own the appropriate bit for ceramic tile

Standard drill bits won’t function on the tile, but don’t worry. Glass and porcelain need to be drilled using diamond-tipped bits, while ceramic tile can be drilled with a carbide bit. While that may seem pricey, a 14-inch diamond-tipped tip costs less than $20, and a similar-sized carbide bit costs less than $10. Buy the diamond bit if you’re unsure. Any kind of tile can be drilled by it.

Step 3: Layout the wall for success

It’s advised to measure three times and drill only once because drilling a hole in a tile wall in the wrong spot can have serious repercussions.

Step 4: Drill slowly

The tape not only makes marking the wall simpler but also prevents the drill bit from slipping when drilling the initial hole. In order to ensure that the hole is placed where you want it, go slowly, especially at initially. Once the hole has been dug, you can speed up the drill, but don’t do so constantly. The hole can be drilled with moderate speed and steady pressure without overheating the drill bit.

Step 5: Speed up at the end

When the bit penetrates the tile, the resistance will alter. You can now increase the drill’s speed while reducing the pressure. By doing this, the hole can be extended into the drywall or backer board with little harm. After you have finished drilling, install the anchors, fasten the hardware, and clean up the slight quantity of dust.

Tips and Tricks

Make a template of the hinge holes out of plywood or plastic sheet if your task is particularly challenging and/or you want complete trust in the results. Determine the location on the wall, then hot glue the template to the tile in that location. At a 90-degree angle, insert your bit or hole saw into the holes.

Your holes will be exactly orientated, and you won’t have to worry about the bit wandering with an exact plan. Even a small amount of masking tape can be quite helpful since it provides a means to mark the tile and prevents the drill bit from shifting initially.

Both the drill bit and the tile might become overheated if you drill too quickly and firmly. The bit will immediately get dull, and the temperature will increase. Heating tiles could cause them to break. Avoid drilling too close to a tile’s edge because doing so increases the chance that the tile may be damaged.

Reduce the drill’s speed and avoid using the hammer feature. Masking tape can be used to identify precisely where you want to drill while also protecting the tile, making it easier to drill through the tile neatly. Then, using a tile/glass bit and a reduced drill speed without using the hammer, slowly drill through the tile.

Why do you need Lubrication?

Use water to cool the tip of the drill bit when drilling through porcelain tile. By doing this, heat buildup—a surefire cause of fractures—will be avoided. The water will combine with the dust created during drilling to create a paste that will serve as the necessary lubricant. In this manner, you can create a tidy hole and store your drill bits for later use.

What about the Pressure?

It is well known that pressure increases friction rather than drilling speed. As a result, it’s essential that you move slowly and maintain mild pressure. As we previously stated, fractures are messy. Thus, we are attempting to prevent them. It’s also crucial to exert as little pressure as possible as you move closer to the hole’s terminus to prevent cracking on the other side when you finally get through.

Furthermore, avoid using hammer drills with diamond drill bits. This is because it will either split or mushroom, which will make it unusable for any subsequent work.

What to Consider When Choosing the Best Drill Bits for Porcelain Tile?

The best drill bit for tile is considerably different from the best drill bit for wood or steel, despite the fact that many drill bits may initially appear to be identical. The best drill bits for tile should also take a variety of materials into account.

Types of Bits

Almost all drill bits, whether for drilling wood, metal, masonry, or tile, are constructed of high-speed steel (HSS), which is durable and reasonably priced. The bit’s tip is coated with a variety of materials since it might quickly lose its sharpness when drilling hard materials like tile.

The most used tip coating is tungsten carbide, a compound of tungsten and carbon (commonly just referred to as carbide). These tops keep their edge longer since they are extremely strong and heat resistant.

 Industrial diamonds that are in powder form and fused to the drill bit under extreme heat and pressure are less frequently employed. They are usually used for hole saws and rarely for ordinary twist drills.

Type of Tile and Tips

The choice of the drill bit will depend on the type of material used to make the tile. Unglazed terra-cotta tiles are common for rustic design and are quite supple. A carbide-tipped masonry bit will last longer, but a basic HSS bit will work just as well. The most popular type of tile used in bathrooms and kitchens is probably ceramic. Once more, a masonry drill bit with a carbide tip is a wise choice.

A drill bit with a diamond tip is advised because porcelain is a tougher material. The same is true for tiles made of stone and glass. There are some exclusions. Some manufacturers have created more effective drill bit designs, particularly the spear point, which enables the use of carbide-tipped versions for materials like glass.

Quantity and Size

Purchasing a single drill bit is frequently an affordable choice when only one or two holes are needed for a certain operation. It depends on the sort of bit, though, as they can cost many dollars each. Purchasing a drill bit set is unquestionably something to think about if drilling tile is going to be a regular task. The tiniest drill bits are typically 1/8-inch or smaller.

Although alternative designs may be larger, the largest twist drill kinds are rarely larger than 1/2 inch. Making a small “pilot” hole before drilling the larger hole is standard procedure when drilling in tile because it might be challenging to handle large bits on a bright, glazed surface.

How We Chose the Best Drill Bits for Tile

I have a lot of experience drilling tile because I am Diyer, who has totally renovated two homes. Our decisions were influenced by our experience and extensive product study. While it is common to practice defining a set of preset selection criteria for these articles, in this instance, it was crucial to find high-quality solutions for a variety of unique drilling situations.

Because many of the leading drill-bit manufacturers are not well-known, brand reputation matters less than it does with products like power tools. Though quality and endurance are essential elements, we also consider customer feedback when making our judgments. Value for money was taken into consideration as always.

FAQs (Frequently Asked Questions)

How can tiles be drilled through without breaking them?

It’s crucial to use the proper drill bit. Standard drill bits cannot penetrate the surface, causing the tile to break when too much pressure is applied. Mark the location of the hole with masking tape. This will also give the bit its first grip. Holding the drill securely, apply pressure slowly and steadily. Do not use the hammer action until you have drilled through the tile if you also need to drill the masonry or concrete that is beneath the tile.

How do I tell the difference between a ceramic tile and a porcelain tile?

Porcelain has a smoother texture, but if the tiles are already on a wall, it could be challenging to detect the difference. The glazed top layer of ceramic tile is typically a distinct color from the core, which may appear at the edge. Typically, porcelain has a uniform color throughout.

What protective gear do I need when using tile drill bits?

Wear the proper eye protection while drilling, if necessary. Put on goggles over your spectacles if you usually wear them. Another smart move is a portable dust mask.
