So, when you’ll be putting a hole on your bathroom tiles, you won’t have to go for another bit for the masonry behind it.

By the way, they don’t penetrate the surface but also reduce the breakout to an amazing level. The set is a combination of 5 bits. Two of them are 6mm(1/4″), and the rest are 8mm(5/16″), a 10mm(3/8″), a 12mm(1/2″). So, clearly, you’re totally in charge of the hole-size customization here.

What to Look for Before Buying Drill Bits for Glass?

Drill Bits for Glass Buying Guide

If anyone has told you that you don’t need to think on a different track to get the best drill bits for glass, then it’s probably because they’ve got no clue about them. But with no idea about it, you too can’t find the right set out for sure. So, we say you better check out a few aspects for tracking the right bits for glass such as –

Tip Material

It’s not always about the sturdiest material but the right one, especially when you’re trying to grab a drill bit to cut glass. There’s not lots of material that can pull the job off like carbide tip and diamond sprayed tip. So, make sure your next bits have a tip like that to put a perfect hole.

Drill Compatibility

Not every bit can work with all the drills. So, when you’re picking up your bits check out if they are going to be compatible with your drills or not. After all, you don’t want to invest in a new drill all of a sudden, right?

Surface Type

At the time of buying a drill bit, we usually don’t think of using it on a single type of surface. So, it’s better to go for something that can cover a lot of surfaces or at least the ones you want to work on.

Number of Bits and Sizes

For putting the right-sized hole on a surface you must get the bit of the right size. So, when you’re looking at a set of bits, check out if the sizes are what you need or not. Another thing we’d like to mention is the number of bits. The more the better as you’ll have more scope to use them.

Shank Type

Take this part lightly and you might put yourself ahead for incoming danger. Want to know how? The right shank type helps the drill with having a better grip. Make that loose and it might turn out like shrapnel of a bomb.

Usually, there are two types of the shank types you’ll see mostly – cylindrical and 3-Flat. The 3-Flat one ensures a comparatively better grip compared to cylindrical. But that doesn’t mean cylindrical ones are bad as with the right drill they too can have better grip.

Frequently Asked Questions

Why drilling glass with a normal is a bad idea?

If you’re trying to put a hole on a glass with a normal drill, you might end up breaking or shattering it. On top of that, the flyaway fragments can easily hurt you in the first place. Even if you do manage to do the drilling the hole won’t be precise or neat for sure.

Is it okay to drill steel with the glass drill bit?

We suggest not to. Steel or metal are not the kinds of surfaces glass drill bits can deal with, at least not all of them. So, to be on the safe side, it’s better to keep the bits away from them.

How many holes a glass drill bit can make in its lifetime?

Well, how long a bit will last depend on its material. But usually, they can push the number of holes up to 2000 in a lifetime.

What type of drill bit needs to use for glass?

It’s better to use the Diamond sprayed/coated and Spearhead drill bits. After all, they can get through any kind of glasses except some safety and tempered glasses as they’re made to tolerate massive impact.

Final Words

While picking a random bit for a drill, it’s not important to bang your head every time. But when it comes to finding out the perfect drill bits for glass you definitely need to see things through a different lens. Though we’ve got you the finest bits for glass, it can still feel like a tricky decision.

Well, we say you pinpoint your need first. For example, if you say you’re asking for angled drilling then we’d the DKIBBITH Diamond Core Drill Bits will be the right one for you. But when you can’t ask more than anything but efficient bits with quicker drilling dust removal you better pick the QWORK WD1801.

On the other hand, if you’re more into putting in the different-sized holes, then the 3 Otters Diamond Drill Bit Hole Saw Set will be more ideal. After all, it has all the wider variety of bit sizes you might need on the way. Now you decide which one is the best drill bits for glass for you.
