WHAT IS A HOLE SAW?
The hole saw has a wide diameter, hollow drill
bit around the outer edge with a keen cutting
tip. By connecting to a power drill it rotates at
high speed and cuts accurate holes in bathroom
basins, pipes, and exterior walls. The cutting
depth is constrained by the cup-like shape of the
hole saw, but a range of drill bit types are
available to work around different requirements.
