Here’s what you need to know about how to drill through plexiglass:
1. Use the Right Drill Bit
One of the most important things to keep in mind when drilling through plexiglass is to use the right drill bit. Plexiglass is a relatively soft material, which means that you’ll need a bit that’s specifically designed for drilling through softer materials. A standard metal drill bit will likely cause the plexiglass to crack or shatter, so it’s essential to use a specially designed bit.
A good choice is a carbide-tipped or diamond-tipped drill bit, as these are more suited to brittle materials like plexiglass than standard drill bits. You can find these bits at most hardware stores or online.
2. Prepare the Plexiglass
Before you start drilling, it’s important to prepare the plexiglass to avoid cracking or shattering. One way to do this is to mark the drilling location with a marker, and then apply a piece of masking tape over the area. This will not only help you to see the mark better, but it will also help to prevent the drill bit from slipping or wandering while drilling.
Another technique is to use a punch or center punch to create a small dimple in the plexiglass. This will give the drill bit a starting point, which will help to reduce the risk of the bit wandering or slipping when you start to drill.
3. Set the Speed
When it comes to drilling plexiglass, you’ll need to set the drill to a slow speed, as high speeds can cause the material to melt or crack. A good rule of thumb is to set the drill to no more than 1,500 RPM.
4. Use Light Pressure
When it comes to drilling through plexiglass, less is more. You don’t want to apply too much pressure, as this can cause the plexiglass to crack or shatter. Instead, apply light pressure and let the bit do the work. This will help to ensure that you get a clean, smooth hole without damaging the plexiglass.
5. Keep Cool
Drilling through plexiglass can generate a lot of heat, and this can cause the material to melt or crack. To prevent this from happening, it’s essential to keep the plexiglass cool while you drill. You can use a coolant, such as water or cutting oil, to keep the bit and the material cool. Simply apply a few drops of coolant to the drilling area as you drill.
6. Clean Up
Finally, once you’ve finished drilling through the plexiglass, it’s essential to clean up any debris or shavings. Use a soft, damp cloth or a vacuum cleaner to carefully clean the area around the hole.
Conclusion
Drilling through plexiglass can be a bit intimidating, but as long as you follow these tips, you’ll be able to do it safely and efficiently. Remember to use the right drill bit, prepare the plexiglass, set the speed, use light pressure, keep cool, and clean up once you’re finished. With these techniques, you’ll be able to drill through plexiglass like a pro.
