When working with agate, jasper, quartz, or other hard stones, the right lapidary blade makes a big difference in cut quality, kerf loss, and blade life. Factors like bond type, diamond concentration, rim thickness, and proper coolant flow all affect how smoothly the stone cuts and how much chipping you’ll see on the edges.
This guide gives a good technical overview of blade types and applications for different lapidary materials:
