Hello people:

I would like your knowledgeable opinion regarding the practice of
cutting holes through things other than wood. In my case, I am
wanting to cut two accurate holes (measuring 80mm in dia; 3 1/8" )
through a panel of thin sheet metal attached to high impact plastic,
like the type used in making cabinets for electronics and PCs.
Actually, I've given in to the idea of trying to get around *not*
improving the airflow in an old Sony Vaio case for overclocking and
will bite the bullet on this one (see thread:
http://www.google.ca/groups?q=insu [...] om&rnum=1)

After looking carefully at the piece, I believe that I will get better
results with the holes if I leave the two materials together for the
cut rather than doing each seperately. However, I don't know squat
about hole saws. What grade of hole saw is best for this job? or if
a hole saw is even recommended for this job?

Thanks,

Bruce

What a coincidence, I just asked this question last week in uk.d-i-y.
http://groups-beta.google.com/grou [...] 16b4b5d2f3
Well ok, a 120mm hole and just in the steel case.
Anyway, the diy guys came up with about a dozen different ways and
it caused a little controversy there.

Cutting large holes in system cases:

Fastest and best results (and most expensive):
Chassis punch; a Greenlee 3 1/8" punch, cost - over $200 US [requires
drilling a center hole, ~ 3/8"

Middle of the road (fairly fast and moderately expensive):
Hole saw [circle with toothed edge the diameter of the desired hole]
or cutter [center drill with adjustable cutter that can be fixed to desired
diameter on an arm] Either tool requires a drill press and clamps; position
of hole restricted by size of drill press

Least expensive, slowest; quality of results depends on how much time you
put into the job:
Hand nibbler [drill a 3/8" or so hole near the edge of the hole, insert
nibbler, chew through the metal, following the outline of the desired hole,
~ 1/16" inch per chew; then smooth with file, emery cloth, and/or Dremel
type power hand tool]

Not recommended: jig or sabre saw (leaves ragged edges and marred finish)

I have always found the Dremel Tool with a ceramic cutoff
wheel to do a great job with such cuts. I can have the hole
done and all cleaned up, faster than I can find and setup a
Greenlee punch.

Luck;
Ken

Hi Phil, good to see the hurricanes didn't get you. How's
your goat?

3/8 hole? a drill and a 3/8 metal / all material bit.

when I did that a couple of years ago, I used a metal blade in a jigsaw and
then cleaned up all the edges with a rotary tool(Dremel). IE..I drew the
rough outline using a compass..used my largest drill bit to bore half a
dozen or so holes in various locations on the steel , got as close as I
could with the blade and then used a sanding drum to get right to my lines.

Hey JAD, "(measuring 80mm in dia; 3 1/8" )"

Time to windex the monitor.

OOOOps........on the other hand the cleaning of the monitor cleared up
things nicely. and here I thought I needed a new one.

OP -craftsman metal hole saw..with a dremal stone for clean up. but much
bigger than a 3/8in.(sigh) the largest one i have is only 2-1/2in..

i thought that sounded funny...the picture of a 3/8 hole saw didnt compute.
Picked a bad time to quit drinking coffee.

Well, it was just a space and a 1 off Not like you used English instead
of metric units and rammed a space craft into Mars, or anything like that.

Ken, thanks for asking: I've left South Florida for Atlanta; ice storms
rather than hurricanes.

The goat opted for the warmer climate!
