8. Technology Description
Diamond core drill bits and diamond hole saws have a hollow center and cut a circle in the material
To create a hole. This results in a hole the size of the drill and a smaller "plug" or "core" which comes from the center. The advantage of a hole saw style drill bit is that is only drills out a small portion of the hole - about 10% compared to a solid drill bit. When drilling in soft materials, a hollow drill bit becomes most effective at about 1", however, in very hard materials, they are preferable to solid bits for even small sizes.
