Drilling a drain hole in a ceramic pot can be a bit tricky, but with the right technique and materials, you can get the job done. The key is to use a diamond-coated drill bit, which is specifically designed to cut through ceramic materials.
Start by marking the spot where you want to drill the hole with a piece of tape or a marker, making sure it's centered and even. This will give you a clear target to aim for.
A good rule of thumb is to use a drill press for more precise control and a steady hand. This will help prevent the drill bit from slipping or wobbling, which can cause the pot to crack or break.
If you don't have a drill press, you can still use a handheld drill, but be sure to keep your hand steady and apply gentle pressure to avoid applying too much pressure, which can also cause the pot to crack.

Drilling a Drainage Hole
Drilling holes in ceramic is much easier if you have the right drill bit. A masonry bit is not a good choice for vitrified materials like ceramic.
You can buy spade/3-point/spear-point drills at most hardware stores and big box home improvement stores. These drills are also called "spear-point" drills and are best for drilling terra-cotta containers.
To keep your ceramic pot from shattering, drill your first drainage hole using a 3/16″ bit, with the painter's tape as a guide. Drill slowly and with even pressure.
Using increasingly larger drill bits, slowly widen the drainage hole. A 1/2″ hole is a fairly standard size for most plants.
To keep the drill bit cool, occasionally dip it in water or use a spray bottle. This will help prevent the bit from overheating and cracking the pot.
A carbide-tipped glass and tile bit is a good choice for drilling ceramic pots. Use a piece of masking tape on the drill site to help prevent chipping.

Here are some general guidelines for drilling a drainage hole in a ceramic pot:
Remember to smooth any rough edges with sandpaper after drilling the hole.
Planning and Preparation
To start drilling a drain hole in a ceramic pot, you'll need the right drill bit. A masonry bit is not recommended for vitrified materials like ceramic, as it works poorly for harder materials.
You can find spade/3-point/spear-point drills at most hardware stores and big box home improvement stores. These drills are also known as "spear-point" drills, and they're the best choice for most ceramic containers.
Drilling into ceramic can be challenging, but using the right drill bit makes a big difference. A core drill may be necessary for highly vitrified materials like glass or extremely hard ceramic.
It's essential to keep the drill bit cool while drilling to avoid breaking the pot. You can do this by immersing the container in water or a 50/50 mix of water and antifreeze as you drill.

Step-by-Step Instructions
To drill a drain hole in a ceramic pot, you'll need a few basic supplies. You'll need a power drill, 3/16″ – 1/2″ masonry bits, painter's tape, a ceramic pot, and your favorite plant.
Mark the holes where you want to drill using painter's tape, typically in the center of the pot. This keeps the drill bit from moving around before you get traction.
To keep your ceramic pot from shattering, drill your first drainage hole using a 3/16″ bit, with the painter's tape as a guide. Drill slowly and with even pressure, taking a few minutes to complete.
You can widen the drainage hole using increasingly larger drill bits, slowly drilling through the base of the planter. A 1/2″ hole is a fairly standard size for most plants.
As you drill, you can increase the speed of your drill once you see a hole forming in your pot. You should also drizzle water on the pot to keep the drill bit from getting too hot and help drill through the surface.
