Cutting A Hole In A Steel Door
How do you install a door knob on a
metal door? What tool to you use to cut through the steel?
Read about the procedure in my
article
Cutting A Deadbolt Hole In A Metal Entry Door.
This job requires a good quality BI-METAL hole
saw. Expect to pay $15 or more, it's money well spent. I would
remove the door and lay it on saw horses, with some sort of
padding to prevent scratching the paint.
The other problem is cutting the hole on the edge of the door.
Depending on the door's construction, you may need to
do some metal cutting to get the rectangular cut-out that
the latch MAY require.
Some door latches only need a 7/8" round hole.
Many steel doors have a wooden edge that can be
drilled with a simple spade bit, as shown in the article
referenced above.
