A diamond blade for granite is always used in this type of granite cutting. You can now find out what special features these cutting discs can have and how they are to be used.
3. Angle grinder cutting granite with granite diamond cutting disc
This combination is most commonly used by DIYers, plumbers and tilers. For the simple reason that here the granite is already in its perfect form, for example granite tiles. These small granite elements can be worked on with the angle grinder.
Choosing the right granite disc is relatively easy because only a 115 mm or 125 mm diamond cutting disc is suitable for the angle grinder. The granite disc should be designed for cutting hard tiles such as porcelain stoneware. These are perfectly capable of cutting granite with an angle grinder.
Cutting granite requires patience and accuracy to achieve the desired result.
What steps do I need to follow to cut granite with the angle grinder?
- Measure the granite piece precisely. Mark the desired cut edge on the granite surface with a washable pen.
- Place your object on a surface that is slightly elevated and the desired cutting edge is in the air.
- In the best case, you use a guide rail that helps you to cut your granite piece as straight as possible.
- Plunge into the edge area and cut along the raw edge. Don't apply too much pressure and let the cutting disc do the work.
- Check the cut piece for accuracy and make sure the edges have not chipped. In the event of damage, you can resharpen and clean it with our various diamond grinding pads .
4. Cut granite with the table saw
The table saw is the most ideal machine for cutting granite. This is due to the use of water. As described above, the use of water is helpful when cutting all materials, especially rock. It provides additional cooling and increases accuracy. Also, the cutting table is the only option for cutting large format granite pieces.
Good to know: When cutting granite with a table saw, you must use a wet cut diamond blade. Depending on the machine type, these can be purchased in diameters of 230 mm x 25.4 mm, 300 mm x 25.4 mm, 350 mm x 25.4 mm.
- Measure the granite piece precisely. Mark the desired cut edge on the granite surface with a washable pen.

- Start the cutting process and carefully guide the workpiece towards the cutting blade.
- Make sure the cut goes all the way through the granite. Again, don't apply any pressure and let the machine do the cutting.
- Check the cut piece for accuracy and make sure the edges have not chipped. In the event of damage, you can resharpen and clean it with our various diamond grinding pads.
