Choosing the Best Drill Bits For Glass in 2017 – Buyer Guide

If you walk into any home improvement store, you’ll find an entire aisle dedicated to drill bits. Individuals, kits, long, short, bits for masonry, bits for metal, bits for wood--the list goes on.

So, what happens when you want to cut glass for your next do it yourself project? Where do you even start?

Glass is one of the most difficult materials to cut because it is prone to shattering and cracks so easily. Well my friend, we’ve compiled a list of the best drill bits for glass on the drill bit market today.

How to Choose the Best Drill Bits for Glass

So, how do you choose the right drill bit for your job?

The following topics are things to consider while searching for choose the right drill bit for glass:

What should the drill bit be made of?

To cut glass properly and without shattering, drill bits must be made of either tungsten carbide or diamond. All other drill bits made of different materials are made for drilling through wood, plastics, and masonry.

It’s important to select the correct drill bit material, because, without a tungsten carbide or diamond coated drill tip, the drill will shatter the glass.

How many Drill bits should I purchase?

Typically, drill bits for glass are not sold separately. However, some drill bits come in packs of four, while others come in packs of ten.

Just how many drill bits do you really need?

We recommend at least a four pack, because Do It Yourself projects take a little bit of practice. Plus, drilling with a sharp bit is infinitely easier than drilling with a dull bit

What Size should I get?

Drill bits are either measured in millimeters or inches. The typical drill bit measures between 1mm and 50mm, or 1 ½ in. These sizes are available in various four-piece kits, and depends on the type of project you’ve decided to take on.

Smaller, more precise cuts will require smaller drill bits, while larger drill bits are used for bigger projects like drilled holes in the glass, or glass edges

What kind of power source do you have?

You need to be sure that your drill bits will fit into the electric tool that you have purchased. Drills, flex shafts, and dremels are all different tools that drill bits can attach to in order to work; while some drill bits are universal, not all bits fit every power tool.

Circle-shaped or spear-shaped?

Again, this depends upon the project. Circle-shaped drills are for--you guess it--drilling perfect circles into materials. These drills work well for drilling holes for wires, piping, and even smaller holes like jewelry.

On the other hand, spear-shaped bits are one specific point of drilling, and, therefore, spear-shaped drills are best for designs and working with smaller, more delicate materials.

With all of these things to consider, it’s no wonder selecting a drill bit for glass is a tough choice. Don’t worry though, we’ve found the top ten kits for drill bits to cut glass and listed them out for you here.

Final Verdict

Many factors play a part in which drill bit you’ll be using to cut glass. Are you designing jewelry, or cutting a circle in a wine bottle? How much drilling does your project call for?

Personally, I recommend a diamond-coated drill bit with grooved edges for extra adhesion, which makes the bit last longer, but it all depends on what your project calls for.

If you are creating a craft that calls for precision, smaller spear-shaped bits will work best. On the other hand, if you’re drilling a hole in a glass tank for an aquarium, then a circular-shaped bit would be best for you.
