If you are looking for a depth stop for the Forstner bits you inquired about
in your second question, Woodworker's Supply has a patented stop for such a
bit.

If you are looking for an efficient and non-marring depth stop for a
standard twist drill, I use a short section of 3/4" wooden dowel in which I
have drilled a hole through with the intended drill bit. After chucking the
bit in the drill, adjust the depth of the drill bit in the chuck with the
length of dowel and use it to "stop" the depth of the hole your drill. I
have used this method extensively when drilling holes for shelving with
shop-made drilling templates.

Good Luck,

Without having a drill press is there an attachment you can put onto a
hand drill to control the depth of the hole?

Also what are drill bits called that can create a cyclinder hole, for a
CAM? So the bottom of the hole is flat. I assume there are drill bits
for a hand drill that can do this?
