I have a piece of melamine board which is part of a shelving system. I need
to drill a hole 2" diameter through it so that I can pass electronic cables
from one side of the shelf to the other.
The problem is this board is about 2.5" thick and I only have a hand drill.
I practice drilling a hole this big on solid wood and each time when I am
done the hole is not straight, it is skewed or slanted because I can't keep
my hand steady and my penetration is not at perfect right angle. Also I
worry about when drilling through particle board will be even harder, and
when it is almost all the way through the drill will "rip" through the other
side and the laminate surface will be messed up.
Yes, a stick. Honest. Take a 1 x 2 and cut a piece of it off and screw or
nail it to be 90 Degrees to the longer size. Use it like a square. Put the
drill against it as a guide to keep you straight.
Do you know anyone with a drill press? That is the best method. Ask the
guys at work or ask in the maintenance shop. You may be able to get it done
for the cost of a cup of coffee. If you live near me, I'd do it for you.
I'm in CT.
Drill a small hole all the way through. Leave the drill running, and pull
the bit out often to clear the chips out of the bit.
Holesaw some from one side, and some from the other.
Shop drill press sounds good.

Start by drilling a pilot hole just slightly smaller than the bit in
the center of your hole saw. Now drill from each side using it as a
guide. If you want the best results, find a friend with a drill
By the way, at 2.5" thick that shelf is probably hollow or filled with a
honeycomb paper material and not solid. If it were solid it would be
Take care drilling, do each side separately.
They WILL meet in the middle..as long as you drill a small hole first right
through and then use that as a pilot hole to center the holes when you drill
from each side. I still would suggest getting someone with a drill press to
do this hole though if possible, it's MUCH easier to get a good job that
