How does a diamond core drill work?

How does a core drill bit work?

Carbide core drills are generally the cheapest option when it comes to core drilling. The drill bit itself features carbide “teeth” that surround the circumference of the drill bit. Once rotating, these teeth bite into the surface you’re working on and cut their way through creating the required hole.

What do diamond Drillers do?
