Objects made of glass usually provide a very attractive appearance. However, drilling this material requires some preparation to get it right, so if you’re doing a glass decorating project, it’s in your best interest to know how to drill glass correctly.
When you’re trying to drill glass, you have to be very precise, as it’s a particularly brittle material. So whether it’s a small hole or a larger diameter opening, it’s important to work carefully to ensure a flawless, break-free result. In this sense, the first thing we must take into account is the choice of tool and the correct organization of the workspace to guarantee fast and trouble-free drilling.
Tools needed to drill glass
You must take special care when choosing the tool, as this can be essential to make an accurate hole in glass. In this sense, you will need special equipment depending on the size of the hole you want to make. For small diameter holes , you should have a variable speed drill or a drill press. Also, it’s good to have a tape measure, a marker, a 3 or 4mm diamond or tungsten drill bit, another drill bit of the desired diameter, and a spray bottle of cold water on hand.
On the other hand, if you want to punch a big hole in glass, all you need is a circular suction cup glass cutter, specially designed to make big circles on glass , just like in action movies where the character makes a cut on the glass to remove the piece and pass through it. Also important is protective clothing and accessories, such as goggles and gloves. As for clothing, the same clothing as that used to cut with the chainsaw is recommended.
Steps to make a small hole on the glass
The first thing you should do is place the glass on a completely flat and stable surface to ensure that the glass does not move during drilling. This process demands a lot of care and concentration. You can then use a marker pen to mark the hole you want to drill into the glass. The next step is to spray water on the glass to moisten and cool it. Similarly, it is important to moisten the drill bit that you are going to use.
Before you start drilling the glass, you have to set the drill to the slowest speed possible. This way, you can decrease the risk of breaking the glass. Afterwards, it is advisable to take a deep breath to avoid moving as much as possible. Also, it is necessary to exert enough pressure and be constant when drilling.
In some cases, you have to stop halfway through the thickness of the glass to flip the glass over and repeat the same procedure to bridge the hole already started on the other side. In this sense, you must cool the glass and the drill bit again with water before resuming the work. On the other hand, when continuing with the drilling, it is advisable to set the drill to a faster speed, but do not exceed 400 rpm, since at high speeds there is a risk of leaving a burn mark on the glass.
Simple trick to make a large hole on the glass
The initial procedure is the same as when drilling small holes in glass. However, in this case, you can drill into glass without a drill, just using a circular glass cutter. To start, you need to draw several grooves in the mark made with a marker, and then just make a circle until you get a relatively deep hole in the glass.
Now, you need to tap very lightly on the areas marked by the glass cutter, which will cause the cut part to eventually peel off from the rest of the surface. When finished, it is necessary to smooth the edges of the hole with sandpaper, since the surface may be very sharp or have tiny traces of glass.
Another idea, if you want to make a large diameter hole in glass, is to use a diamond hole saw to make the cut. In this case, it is best to make sure that the glass has cooled properly before cutting it. In any case, remember that you must drill the glass at a very slow, but constant, rotational speed to prevent the glass from breaking.
How to drill a glass bottle for your DIY projects?
In case the glass you want to drill is cylindrical, for example a wine bottle, then you should place it in a wooden vise so that it does not slip. In addition, it is advisable to stick a piece of thick cardboard around the bottle to create a kind of guide and thus obtain a more precise and safe work. On the other hand, when you are nearing the end of the hole, you should reduce the speed of the drill considerably to avoid breakage.
If you are still worried about how to make a hole in a bottle glass, then you should practice the technique of holding the tool. In this case, the most appropriate way is to place the drill perpendicular to the surface you are drilling. In this way, it is possible to achieve a cleaner result. This procedure is very useful if you want to create a table lamp, design a glass vase, make candle holders, make candle holders, among other DIY projects.
To conclude, it is necessary to mention that drilling glass is a job that must be carried out with all security measures. Whether you want to drill a hole in window pane or create holes in glass containers, this is pinpoint-precision work that requires a methodical approach, which is why it is mainly carried out by experienced professionals.
