Factors to Consider When Choosing the Best Drill Bits for Glass

When dealing with glass, you will at one time or the other need to drill a hole in the material. You will, therefore, need the drill bits that give you the most perfect and smooth work. It is, therefore, necessary to know what to look for in these tools. Below is a list of factors that are worth considering:

  • The side holes

When selecting drill bits, you need to get one that will pull out slugs that cause corrosion. The tools with side holes help to prevent damaging or even breaking the glass while working on it. This feature also helps you to get neat and clean holes.

  • Nickel Plating

Nickel-plated drill bits help to offer exceptional resistance to abrasion when drilling. The tools also have tight tolerance as well as reducing the friction, thus producing uniform precision with no edge build-up. 

  • The material Used

The material used in making drill bits play a significant role in the accuracy of holes that you get. It is, therefore, necessary to know what content is best for your work. A diamond tip is ideal if you do not want tiny holes. The tips coated with diamond sand are also suitable in cutting clean holes. You can also pick tungsten carbide coated top as this will work well on your glass without cracking it.

  • The shape of the drill bit

There are different shapes of bits for various surfaces or materials such as hole saw drill bits, counter skin drill bits and those with different angles. Small glass bits have the shape of ordinary bits, but if you are dealing with large sized holes, then you require a hole saw style bit. The saw-style tool helps to stop the edges from chipping and cracking. The hollow core of the drill bit also securely removes the materials drilled from the hole. There are also circular or spear-shaped drill bits with circular bits being ideal for drilling circle/holes in bottles. Spear-shaped tools are useful in the design and working with particular materials.

  • A Flat Handle

Since the handle or shank acts directly on your workpiece, it needs to be flat to reduce slippage while drilling. It also allows for higher torque and greater centring precision. A flat shank also helps you to cope with any type of workpiece by offering a smooth rotation. The tool also enables you to work with little pressure from the upper part of your drill bit, and thus you don’t strain your hand.

Frequently Asked Questions about the Best Drill Bits for Glass

Below is a list of the frequently asked questions about drill bits for glass that we found useful to you:

Q. Which is the suitable drill bit for glass?

Glass is delicate and fragile, and therefore not all bits can be used on it. However, there are generally two types of drill bits that can be used to drill holes on the glass effectively. Tungsten carbide spear-tipped and diamond-tipped drill bits are efficient since they can work on glass without any breakage. For tempered glass, diamond-coated and carbide-tipped are the best options.

Q. It possible to drill through the glass with an ordinary drill bit?

It is possible to drill through glass using ordinary drill bits that are made of materials harder than the lens itself. The right electric drill bit can be correctly used on glass without damaging it.

Q. What material are drill bits made of? 

Drill bits are commonly made of steel that is referred to as HSS (High-speed steel). Some brands heat the bits to high temperatures of up to 950oF to make black oxide bits which makes them rust and corrosion-resistant.

Q.  Is it possible to drill through glass without breaking it?

Drilling produces heat which can break the glass. It is, therefore, necessary to cool the area you are working on by spraying water or placing the object in water as you drill.  It is advisable to drill just halfway through the glass and not break thought it. The glass should then be turned over and cut again from the other side.

Q. How can one tell if the glass is tempered?

Tempered glass has edges that are entirely smooth as a result of the additional processing it goes through. Other types of glass have ridged or scuffed edges, and it is, therefore, possible to differentiate them. You can efficiently run your fingers along the edges if they are exposed. 

Q. Can a Dremel be used to cut glass?

Dremel is a brand of power tools, mainly rotary tools that can be used for cutting wood, glass, plastic, and metals. The device can be used to cut not just ordinary glass, but also plexiglass and also fibreglass.

How to Drill Glass

Final word

Drilling glass is a challenging process since it is prone to cracks and shattering. It is, therefore, necessary to look for the most appropriate drill bits for glass that will not only give you the best outcome but also minimize the risk of breaking your glass. When choosing the drill bits, ensure that they are made of a material that is harder than the glass itself. HSS (High-Speed Steel) is the most suitable material since it can penetrate through the glass without causing any breakages. 

Purchasing a set of drill bits of different sizes is also advisable since you will not need to buy more sets any time you have a different project. The collection should also be made of durable material as well as have diamond-coated tips for accuracy and precision. To get rid of slug or removed materials, ensure that the drill bits have side holes. It is also crucial to select the drill bits with a flat shank or grip to prevent the tool from slipping out of your hands when you are drilling. The flat grip also enhances the stability and efficiency of the devices and makes it quick and smooth for your project.

With the best drill bits for glass, nothing can stop you from achieving your desired goals. So don’t be left behind! Let nothing stop you! Pick what suits you from the above list and drill like a pro!
