Diamond cutting discs are typically made from a metal core with diamond segments attached to the rim or periphery of the disc. The diamond segments are embedded in a metal matrix or bond, which holds the diamond particles in place and helps to transfer heat away from the cutting surface. The bond type determines the durability, aggressiveness, and cutting speed of the diamond cutting disc.

When selecting a diamond cutting disc, it is important to consider the material being cut, the thickness of the material, and the type of tool being used. For example, a larger diameter and thicker cutting disc may be required for cutting thicker materials or for use with more powerful tools. A finer diamond grit size may be preferred for cutting hard, dense materials, while a coarser diamond grit size may be preferred for faster material removal.

It is important to follow proper safety precautions when using diamond cutting discs, including wearing appropriate protective equipment and using the disc at the recommended speed and angle. It is also important to periodically check the condition of the cutting disc and replace it if it becomes worn or damaged.

Here is a general size chart for diamond cutting discs:

Note that this is just a general guide and specific sizes may vary depending on t the intended use of the cutting disc. It is important to choose the right size and type of diamond cutting disc for your specific application and to follow proper safety precautions when using the disc.
