THEIR APPLICATIONS?
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.

cup-like shape of the hole saw, but a 
range of drill bit types are available to 
work around different requirements.
