Cutting a hole in sheet metal seems like a common task,
however doing it right will not only be safer, but can also
improve tool life, cut speed, and cut quality (clean vs. jagged
edges).
1. Start by measuring twice. Use the green pipe clamp
for the dip tube you are installing to help layout where
the hole needs to be drilled, as well as where the
fasteners will need to go for the clamp. Use a center
punch to locate the holes and prevent drill drift.
2. Use the appropriate size drill to make a pilot hole in
the center of the cut. *NOTE* Only the drill should be
used at this point, do not use the drill bit while
attached to the hole saw. When the drill breaks
through, you can damage the hole saw by “punching”
the sheet metal and breaking or bending the teeth.
3. Install the blank pin in the arbor, then thread on the
hole saw. (In a pinch, an old drill bit installed
backwards can work as a guide too) Be sure to set
your drill to low speed and change from drilling to
torque mode.
4. Apply cutting fluid and begin cutting, feathering the
trigger to maintain a moderate speed.
5. Be sure to continuously add cutting fluid to keep the
hole saw cool and lubricate the cut.
