DRILLING IN METAL
Metals such as steel, brass, aluminum sheets,
stainless steel and pipe may also be drilled. Mark
the point to be drilled with a nail or punch.

When drilling in delicate materials such as wall,
it is essential to start with ordinary drilling and
once the tile is pierced, to continue with impact
drilling.
