All hole saws are not created equal. A
cheap hole saw from a home improvement
center or one that has been dropped can
be out of round and will not fit the drill
bushings in our templates.
Shown above is a standard twist drill
bit. They can be used on both wood or
steel doors. Be sure to back out the bit
when drilling to clear chips. Shown above and at right is
a brad point bit. They will
produce a very clean hole in
a wood door. Use at a low
speed and back the bit out
to clear chips. Do not use
on a steel door.
Shown above is a spade or paddle type
bit. Do not attempt to use this in any
drill guide. There is no bearing surface
and you will jam the bit.
Shown above is a tri-flute drill bit. Do
not attempt to use this in a drill guide.
The lack of bearing surface will cause
the bit to jam.
