How To Drill A Hole In A Porcelain Sink

how to drill a hole in a porcelain sink

Porcelain is a type of ceramic that is baked with a porous glazed surface inside. The glazed finish is tough and waterproof, which is why porcelain is ideal for sinks. But that same property also makes them hard to drill. A normal drill will quickly become dull, while a hammer drill will break the porcelain, not drill through it. However, is there any way to successfully drill through ceramic flume using a conventional drill or a specialized drill? Of course! Read on this post to learn about how to drill a hole in a porcelain sink without further ado.

What is Porcelain

Millions of bathroom sinks are made of china, a hardy ceramic. The material consists of two main components: kaolin and petunia. Kaolin, also known as china clay, is a silicate mineral that imparts plasticity and structure to ceramics. Petunse, also known as pottery stone, imparts hardness and translucency to ceramics.

The material is made by mixing several ingredients and then shaping the result by heating them in a kiln at temperatures between 1,200 and 1,400 degrees Celsius. Porcelain has a high level of mechanical resistance, high density and low porosity, ideal for its appearance and durability. Sinks made of porcelain can be pricier, but some styles are less expensive than others.

Things you’ll need

To successfully drill a hole, or multiple holes, in your porcelain sink, there are a few things you need to know. Before we get into the specifics, here’s what you’ll need:

  • Adhesive tape
  • A tape
  • Goggles
  • Ceramic drill bit or diamond drill bit
  • Cutting oil

Step to drill a hole in a porcelain sink

Step 1. Place a piece of tape on the general location where you want to drill. Drilling in avariety finish is easy to avariety, and sticking a piece of adhesive tape can prevent avariety.

Step 2. Measure exactly where you want to drill. Make a mark on the duct tape that will be drilled.

Step 3. Wear safety glasses. Place a ceramic bit or diamond hole saw into the drill chuck. A ceramic bit is easier to control because it acts much like a regular bit. After the work is done, the diamond hole saw can provide you with a smoother entry hole.

Step 4. Press the drill bit to the tape at about a 90 degree Angle and begin drilling into and through the tape. Do not push the drill body too much; Let the drill work. For every 30 seconds of drilling, drop some of the cutting oil onto the bit in contact with the porcelain sink. This prevents the drill from overheating and also removes porcelain particles from the hole.

Step 5. Continue drilling in this manner until you break through to the other side. Repeat the process, drilling as many holes as possible. Finally, you succeed in drilling a hole in a porcelain sink by yourself.

Precautions when drilling holes

  1. Always wear safety goggles when drilling porcelain sinks. If the splinter accidentally gets into the eye, it can cause great pain and injury.
  2. Another important safety issue to consider is overheating. The friction of the drill on the ceramic sink can generate heat, which can cause the porcelain to crack. So don’t drill for a long time, stop drilling after a while and cool down with water to prevent this from happening.
  3. The edges of your porcelain holes can be very sharp. It is essential to smooth them out with a file, but it would also be useful to wear safety gloves during the process to prevent any cuts.
