Diamond hole saws have edges coated with fine diamond particles, making them excellent for cutting difficult materials. The diamond in the hole saw should be cooled with a liquid during operation. You can use a window sprayer, a sponge soaked in water, or a continuous spray of water. Hole saws can also be run dry, but this shortens their service life.
