Do you need to do something indoors or do you have a craft project that requires drilling holes through glass? You can use a conventional electric drill and a suitable drill for this job. The bottom line here is that the material used to drill must be harder than glass.

Steps

Part 1 of 3: Finding the right tool

1. 

   Determine the type of glass you want to drill. You can drill holes in wine bottles, aquariums, mirrors, glass bricks - all kinds of glass in general. However, an important rule is never Drill holes through tempered or safety glass.
   • The tempered glass will be splashed when it comes in contact with the drill. To identify tempered glass, look at the four corners. If it is tempered glass, the manufacturer will engrave it on each corner.
   • Another warning: When using a drill, be sure not to wear loose clothing or long dangling accessories such as necklaces, bracelets, and shirts with long tassels. It is crucial not to wear or wear anything that could become entangled with power tools. Also, wearing goggles and gloves is better.

2. 

   
   
   Buy or use a drill that you already have at home. Use the drill available at home; if not, you can buy conventional electric drills at most tool stores.
   • Drilling a hole through glass doesn't require a special drill - you just need the right bit.
   • However, it is important not to use the drill's full capacity or top speed; otherwise, the glass is in danger of cracking. Think as if you were carving into glass and not drilling a hole through it. Set the speed of the drill and adjust to the lowest setting. This will help you slow down the drilling process.

3. 

   
   
   Choose the right drill bit. You need to choose a drill that is specifically designed to drill holes through glass. This is extremely important; you cannot select any of the available bits. Ask the vendor at the hardware store to help you choose the right one. Glass drills are quite common, and can be purchased online.
   • A carbide drill used to drill glass and tile is also a good option. The carbide drill is shaped like a shovel blade and can withstand the friction of drilling on glass or brick.
   • You can find carbide drills at the tool stores. Just go to the area where the drill is sold and ask the salesperson. One downside to cheap drills, however, is that they are blunt quickly, and can even break.

4. 

   
   
   Another option is to use a diamond drill. These types of drills are used to drill glass, sea glass, wine bottles, glass bricks and other harder materials such as marble and stone. Diamonds are harder than glass, making them the perfect material for drilling hard materials.
   • The diamond drill bits can be used to drill holes about 0.6 cm in diameter or larger. You can choose a round or tubular drill bit. The diamond drill will create a smoother drill hole. Diamond drill bits in the past are often used to drill glass; a single drill can drill many holes and will rarely break if used correctly.
   • For very small holes, you can choose a small diamond drill bit with a hard, flat tip. There are several types of drill bits that are very small, up to 0.75 mm.
   • You can also buy diamond cutters. You need a quick-start automatic punch replacement. These will match the drill. Use the punch for the drill to make the first hole in the glass. Then attach the saw to the drill and place in the hole created with the punch. Drill through the hole.

Part 2 of 3: Preparing to drill

1. 

   Place the glass material in a small box, if it fits. You can use an ice cream box or a plastic tray. You don't want to drill through tables or similar objects.
   • Put some old newspapers on the bottom of the glass container. This is to prevent you from drilling through the box.
   • Another option is to place the glass on a sturdy, sturdy surface. If possible, you should place a piece of rubber or other material underneath, but a glass object right lying close and firmly secured. In other words, don't stand up when drilling a hole or do the same.
   • Always be cautious. Make sure not to drill in a place that could damage furniture, and remember that the drill wire is not placed near water.

2. 

   Stick a piece of cardboard or tape to the glass. This is to prevent the drill bit from slipping when starting to drill. You can use a cake box for this purpose.
   • Another way is to glue the inside and outside of the glass to be drilled with packing tape or paint masking tape. This will prevent the glass from breaking.
   • Tear off two pieces of tape. Stick two pieces of tape crossed over the X-shaped tape over the point you want to drill. Never drill a hole less than 2 cm from the edge of a glass.
   • Make a mark on the tape at the point where you want to drill the hole. This will help you locate it when you are about to drill.

Part 3 of 3: Drilling holes

1. 

   Start drilling at the lowest speed. Drilling is recommended for hard materials; You can find online drill speed recommendations for a variety of materials, including glass.
   • Attach the small drill to a multi-speed drill. Make sure to attach tightly. It is best to start with a drill of 1/8 "or 3/32" in size. You should only make a hollow hole in the glass first.
   • Then remove the cover plate or tape and drill faster at about 400 rpm (400 rpm) If drilled too fast, the drill can cause scorch marks around the drill head. If necessary, you can replace the larger drill to open the original hole. The first hole is the "guide" hole. It will guide the larger drills you continue using until finished.

2. 

   Reduce drilling pressure and speed even further when the drill is about to penetrate the glass. When drilling for glass, you should keep your drilling speed low or medium. When you are about to penetrate glass, you need to slow down even more, as the glass is most likely to break then.
   • If you press the drill too hard, you can break the glass. You need to keep the drill bit perpendicular to the glass surface to prevent chipping. If you are new to this job, just use light pressure to avoid making a big mistake.
   • Alternatively, drill only halfway through the front, then flip to the other side (carefully) and drill until it clears the hole on the front.

3. 

   Use coolant to prevent the drill bit from overheating. This is very important. Pour some oil or water over the area where you are drilling. Water is the most commonly used coolant for drills. You will need more cooling if you drill a harder surface. Coolant will keep the drill bit smooth and cool. If the glass gets too hot, it can crack and break.
   • The coolant can be used before and during drilling.
   • You can pour some water into the bottle and pour water over the hole you are drilling. Water will flow into and out of the hole while drilling and will help cool it down.
   • You can also spray water around the drill bit to keep it slippery. Again, be careful with electrical cords and water. Try pouring water into a spray bottle and spraying it while drilling. If white powder forms while you are drilling, you should use more coolant and slow down your drilling speed.
   • You can also place a wet sponge under the glass object during the drilling as a coolant. Or you can put water on the glass before drilling - by pouring water over the glass container.

Advice

• Do not use too high a speed when drilling. Glass is very hard and has a high friction, so the bits can break down very quickly.
• Using a punch can help stabilize the drilling force.
• Use multiple drills, starting with a very small tip and gradually replacing larger bits to reduce pressure on the glass.
• Note that the drill bit can chip the edge of the drill hole on the back of the glass, the drill hole in the front will be smoother.
• It is extremely important to always use a respirator. Dust from glass, also known as silica dust, can cause a form of lung cancer, also known as pneumoconiosis.
• Keep the glass cool when drilling the hole. This will help prevent glass breakage and drill tool breakage.
• While it's better to use water, cutting oil can help with your drilling - only sparingly.

Warning

• Glass is very brittle and sharp. Be careful when handling glass, use gloves, and wear a mask and goggles when drilling holes.
• Glass debris is dangerous to the eyes, so wear appropriate ANSI standard goggles.

What you need

• The drill has a variety of speeds
• Glass drill bits
• Solid work surface
• Tape
• Containers that contain water or water spray
• Safety glasses (ANSI standard): Any "ANSI" glasses will have "Z87" printed on the frame.
