Buyer Guide to Choosing the Right Drill Bits for Cutting Glass

While it may take some time to research which drill set is perfect for your glass project, you can skip the research and purchase one of our top recommendations. This buyer’s guide will tell you what to search for and how to acquire the most excellent option for glass if you want to know how to select the best options for drill bits in the future.

Tip Material

The effectiveness of a drill on glass largely depends on the composition of the drill tip.

Using carbide drill bit tips like the ones we provided will prevent your glass material from shattering while drilling and will provide a cleaner hole that better secures the screw. With everything in place, you can expect your project to go off without a hitch and have a better quality result.


Depending on its length and diameter, these tasks can be accomplished with a particular drill bit. Options with about half an inch diameters may be unsuitable for tasks that call for a smaller screw. Too large of a hole, and the screw will fall out. This might derail your efforts and prevent you from completing the job as planned.

If the hole is drilled too tiny, the screw will have to exert too much force against the hole’s interior, perhaps cracking the glass.

It might be difficult to remove when a screw is too tightly screwed in. Also, if you don’t have the right size screwdriver, removing the screw might produce a break, which would damage your hard work.

Convergence of Drills

A power drill will only work with certain types of drill bits.. You don’t want to waste money on a glass drill bit that won’t fit your drill, so be careful while selecting.

The Various Surfaces

In most cases, the cost of a drill bit is justified by the number of materials it can pierce. If you can’t locate a suitable drill bit for your chosen surface, choose the least efficient one.

What Kind of Drill Bit Is Ideal For Glass

Design-wise, two main categories of drill bits are optimal for use on various stone and ceramic materials, including glass, tiles, marble, granite, and slates. Both are useful drill bits, but your choice will depend on the type of glass you plan to drill through.

  • Spear Head drill bits
  • Diamond-coated drill bits

Spear Head Drill Bits for Glass

This drill bit type’s spear shape is the name’s inspiration. This one offers superior accuracy compared to diamond-coated drill bits, making it an excellent choice for smaller jobs. But, unfortunately, this drill bit, made of tungsten carbide, isn’t the most popular either.

Drilling with a spearhead drill bit requires constant water or water lubrication, so keep that in mind. However, if you drill through the glass, you risk damaging the drill bit and the glass itself due to the high temperatures generated.

Glass-Drilling Diamond Bits

It’s the standard for drill bits designed to break the glass. Mirror, window, tile, door, and aquarium glass are some materials that may be drilled with a diamond drill bit. This drill bit is made specifically for cutting glass and comes with a diamond coating or tip. Allowing you to drill through the coating without damaging the bit.

Instructions for Using Glass Drill Bits to Make Holes in a Mirror (Step By Step)

Glass is a fragile material; thus, drilling into it is not as easy as drilling into wood. In contrast, the hardness may be diminished with the proper drill bit and technique. To drill through glass, you need to use a sharper drill bit and more suitable for the task. To remedy this, use any of the aforementioned glass drill bits..

Before heading out for practical, make sure you have these things:

  • A variable-speed drill
  • a level ground
  • Cardboard
  • Marker
  • Lubricant (oil or water) (oil or water)
  • Strapping tape for painters
  • Armor for self-defence (gloves, safety glass, long tight pants)
  • Something to wipe your hands on
  • Cushion

Get ready

Cutting through glass presents a high risk of injury due to the shards of glass that can be released throughout the process. Therefore, all necessary safety gear must be worn before the start of the practice.

Fix the mirror in place and make a note of the coordinates.

The mirror should be placed on a flat, stable surface and then secured to the cardboard using painter’s tape to prevent it from moving around during drilling. Cushions can also regulate the hardness level, which can help reduce or eliminate movement. After that, use a permanent marker to indicate where you want to make your hole.

A diamond drill bit should be inserted.

When starting to drill, it is best to use a little diamond drill bit to make the pilot hole. It’s as efficient as you can make it, even if a huge hole is needed.

Begin the drilling immediately

To get a better start:

  1. Start the drill and hold it at a 45 degree angle to the mirror.
  2. Don’t freak out and break the glass without thinking it through.
  3. Remember that the mirror is easily cracked or broken if you use too much force, so just let the drill do its thing.

Maintain a level drill

After drilling the primary hole, the drill should be angled at a ninety-degree angle against the mirror for the following stage. The next step is further drilling.

Put on some grease

Applying oil to the drill regularly will protect it from overheating. The drill bit and other surfaces, such as glass, can be damaged by excessive heat.

Quietly finish the task at hand.

Again, keep your cool and complete the work without losing your composure. It might take 4–5 minutes for a standard mirror and 5–10 minutes for a mirror made from thicker glass. For extra-thick panes of glass when cracking is a concern, you can drill from both ends.

Can a regular drill bit drill glass?

A drill bit consisting of diamond or tungsten carbide is your best bet for drilling through glass. Avoid using a hammer drill if you’re using a diamond drill bit, as this will destroy the drill bit.

What kind of drill Do I need to drill glass?

To avoid damaging the surface, a carbide bit designed for cutting glass and tile should be used (see photos). These bits are commonly sold in home improvement stores with other drill bits and ceramic tile equipment. However, drilling into glass can be difficult due to the material’s high smoothness and hardness, which causes the bit to wander.


Glass is hard and brittle, making it a complex surface to drill through and necessitating the use of specific drill bits.

Thankfully, it is feasible if you have the correct equipment and methods.

The QWORK 5 Pcs Set Multi-Material Drill Bit Set for Glass is my favourite of the six options we discussed for the best drill bits for glass. It is possible to cut down on drilling time with this masonry drill bit set thanks to the arrowhead shape and spear-sharp tips.
