Glass finishing isn’t just as simple as acquiring the right equipment for your chosen method; sometimes, you need butter-soft glass, so nearly any technique will suffice.

It can be frustrating to drill a hole in the glass. The slightest twist or jiggle of the power tool will break the fragile material and ruin your project. However, with only top glass cutting drill bits, you can complete your task without damaging any other projects that may have been on hold for now as well.

Here take a quick look at our top picks of glass cutting drill bits.


Many drill bits can be used to cut through glass successfully, and it is essential to wear gloves so you won’t get hurt by any broken shards. The best type of bit depends on what kind of material the person needs for their project. 

For example, tungsten carbide spear-tipped drills work well with more complicated types of materials like stone or concrete, while diamond bits do better when dealing with softer substances such as plastic.

However, they need a coolant to keep them from overheating, which means there’s an extra step involved before using these kinds of drills. There are also diamond-coated drill bits available if someone wants all-around protection against anything – even scratches.

Q: Can you cut glass with a standard drill bit?

A: It’s not as easy to drill a hole in glass using the wrong tool, but you can do it if you’re determined. The trick is making sure that there are no air bubbles inside of your bottle before drilling because they’ll shatter the entire thing when their pressure increases and creates an explosion too powerful for regular water to prevent from happening.

Q: How do you enlarge a hole in glass?

A: When you heat the glass, it becomes more malleable and can easily be pushed out of shape. If needed, use a tiny screwdriver that fits in the hole already ー. First, put it inside, then slowly push outward until it’s big enough for your fingers to fit through. Make sure not to cool down again, or else the heated piece may become brittle and break before finally extracting from whence it came.

Q: Can you use a diamond drill bit on glass?

A: Diamond drill bits are perfect for drilling holes through almost any hard material. These tools work quickly and effectively when you need them to, giving a clean cut with minimal effort on your part so that the hole can be used as soon as possible.
