It is possible to cut marble without a wet saw, but it is not recommended. The reason for this is that cutting marble generates a lot of heat, and without water to cool the blade and the marble, the marble can crack or become damaged. Additionally, cutting marble without a wet saw can be very difficult and time-consuming, and you may not be able to achieve the precision and accuracy you need for your project. If you must cut marble without a wet saw, you can try using a diamond-tipped blade on a circular saw or angle grinder, but proceed with caution and be aware of the risks involved. Overall, it is best to use a wet saw for cutting marble.
