3 Tools For Grinding Glass

There are various forms of grinding tools available in the market, and these grinding tools are used to grind a sheet or block of glass into shape.

Grinding a glass into shape is no less than an art, and in order to do it properly, we will have to know what these tools are and how to use them.

In this guide, we will discuss three tools for grinding glass and how to use those glass grinding tools.

3 Tools For Grinding Glass And Their Uses

1. Carborundum File

Carborundum File To Grind Glass

A carborundum file is one of the most inexpensive ways of grinding glass.

This file is generally made up of the carborundum stone or crystal. It is a man-made crystal that is made by a combination of silicon and carbon.

The elements are combined together to produce a crystal that shines when it is held against a gray or black background. The crystal shines in the colors of blue, purple, green, and gold.


Carborundum is widely used in the glass sculpture industry as an abrasive product that polishes, grinds, and cuts glass pieces.

How To Use A Carborundum File To Grind Glass

  • Using a carborundum file is quite easy. Lay down the piece of glass you want to grind and take out your glass grinding tool, Carborundum file.
  • Take a pot of water and dip the file into the water. Keep the water pot near you as you will have to dip the file into the water during use as well.
  • Place the file at an angle on the edge of the glass and slide the file side to side to grind the glass. Grind the glass to whichever shape you like or want.
  • The method works better if you place the file at an angle of 45 degrees to the glass piece.
  • Make sure to remove the glass dust after completing the glass grinding. Keep a cloth or plastic sheet underneath for convenience.

2. Diamond Pad

Diamond Pad To Grind Glass

A diamond pad is technically a small plate-like surface that is covered with a coating of diamond dust or powder.

The pad generally comes with foam on the back that makes it easier to grip the product.

The diamond pad is ideal for repairing, grinding, and polishing glass, ceramics, stone, and so on.

The configuration of diamond dust is usually stronger than glass; thus, it can easily cut and grind glass.

Diamond pads are available in 4 different grit ratings. The grits usually range from 60 to 400 grits.


60 grits are technically used for hard scrubbing, while the 400 grits are commonly used for smooth polishing. 

How To Use A Diamond Pad To Grind Glass

  • Using a diamond pad is quite easy and very similar to using a carborundum file.
  • Take the diamond pad and place the plate-like surface towards the glass at an angle.
  • Rub the diamond pad side to side against the glass piece and grind it.
  • Remove the glass dust from the piece after grinding is complete.

3. Set Of Cylindrical Grinders

Set Of Cylindrical Grinders

Last but not the least, a set of cylindrical grinders is a great glass grinding tool.

Cylindrical grinders come in small and large sizes. The small cylindrical grinds come with an outer casing or shell to ensure a better and easier grip.

We generally use a cylindrical grinder to grind glass in order to give it a rough polish. However, it does not have the ability to provide a fine or smooth polish.

In a set of cylindrical grinders, two grinders are put into their outer casing, and the casings are joined together by a screw or magnet.


In manufacturing units and large glass factories, we generally use computer-operated large cylindrical grinds to grind glass, ceramics, stones, and many more objects.

But for easy use or at home, we generally use manually operated small cylindrical grinds.

How To Use A Set Of Cylindrical Grinders To Grind Glass

  • Take the set of cylindrical grinders and make sure that the grip is secure and comfortable.
  • Place the glass piece between the two-cylinder grinders.
  • Move the grinder from side to side to grind the glass and roughly polish it.
  • Clean the glass dust once you are done.

Tips And Cautions When Using A Glass Grinding Tool

If we talk about things honestly, then using a glass grinding tool is not as simple as it looks. But there are certain tips and tricks that will make it a bit easier for you to grind glass.

1. Always Use Protection Eyewear, Mask, And Gloves

As we all know, glass is a brittle object, and when it is cut, the sharp edges can often cause injury.

When it comes to shaping a glass piece or structure, you will often find a few sharp shards here and there.

Wearing protective gloves while grinding glass will protect you from the injuries caused by the sharp glass pieces or edges.

When we grind a piece of glass, the grinds come out as glass dust. This dust can easily get into our eyes and nose, which can often cause severe damage.

Therefore, experts always recommend wearing proper eyewear and a dust mask while grinding glass to avoid any accidents or harm caused by the glass dust.

2. Make Sure To Trace Out The Shape First

We usually grind a glass piece to turn it into a beautiful shape or structure. But a mistake that many of us make is that we do not trace out the shape before grinding the glass.

This often ruins the shape, and our hours of hard work go to waste. Hence, make sure that you always trace the shape you want before you start grinding.

You can either draw on a piece of paper and put the glass on that paper. Or you can draw on the glass with a temporary marker or pen.
