A marble cutter is a power tool used for cutting marble, a type of natural stone that is widely used in construction and building materials. Marble cutters are designed to make precise cuts in the stone, and they typically use a continuous rim diamond blade that rotates at high speed. The blade is guided along a track or guide, allowing the user to make straight cuts with a high degree of accuracy.

Marble cutters come in different sizes and styles to suit different needs, and they can be powered by either an electric motor or an internal combustion engine. Some models are handheld and portable, while others are mounted on a worktable for added stability.

When using a marble cutter, it's important to follow the manufacturer's instructions for proper use, as improper use can cause damage to the tool or result in personal injury. Additionally, it's important to wear protective equipment, such as safety glasses and gloves, to protect yourself from flying debris and dust. In addition, a good practice is to moisten the stone before cutting, as this helps to reduce dust and keep the blade cool, which can extend its lifespan.
