Good To Know

Q: Do I really need to use water with these dry diamond drill bits? A: No, these bits feature an internal cooling wax that lubricates the cutting edge during dry drilling, though using water can still extend their total lifespan when cutting extremely hard granite.

Q: What technique should I use to start drilling with these hole saws? A: Start drilling at a 45-degree angle to establish a notch, then slowly bring the drill perpendicular (90 degrees) while applying light pressure in a circular motion.
