  1. 1

    Obtain a diamond tipped blade. These are the preferred blades for a lapidary saw because they cut precisely through the stone. If a diamond tipped blade is unavailable, an alternative is iron blades or brass blades. However, these must be cooled with grit and water before use.

  2. 2

    Remove the coolant from a normal drop saw's coolant bin. This will not be effective for the lapidary saw. Replace the coolant with an even mixture of water and grit to be used for cooling.

  3. 3

    Unscrew the bolts on the drop saw that are holding the current blade in place. Replace it with your diamond blade. Diamond blades are designed to fit many different bolt sizes, so fitting it on will not be a problem.

Tips and warnings

  • Do not try to force any excess cutting power or you will damage your saw. Wear safety goggles when cutting.
