Very true.

You can also make a thin cardboard pocket (or use a plastic container) and tape it to the underside of the panel to contain most of the sawdust that would otherwise end up inside the bartop.   ;D

Another approach is to clamp some scrap wood to the inside to minimize blowout, but this might be difficult depending on where you need to drill the holes.
- Not sure from the pic you posted if you have the access and right type of clamps for this approach.

It's pretty easy to make a depth stop for a Forstner bit.

Cardboard is too flimsy, but you could use a hole saw cutout like this.
- You will need to drill out the center of the cutout.
- If you don't have a holesaw, drill the center hole for the cutout and cut the body with a jigsaw.
- Leave a path for the chips to escape.

As long as you can keep the bit perpindicular while drilling, you can use a regular power hand drill.
- I've drilled free-hand with Forstner bits before -- no problem as long as you can control the angle and feed rate.

If your hands are shaky or you can't maintain the proper angle, use a drill guide as mentioned earlier.

I noticed it doesnt have a hex shank for use in my hand drill. Is that gonna be a issue or will it be fine?

Almost all drills have an adjustable 3-jaw chuck -- either keyed or keyless.

 

It will be fine as long as you properly tighten the bit in the chuck. (i.e. not loose or at an angle)

If you have a drill that only accepts hex shanks, there are hex drive chucks.   ;)

slybunda:
What was i thinking. Regular drill bits i use are round and not hex. Hex is just the screwdriver bit i have.
Will get those forstner bits ordered.

Hole saw all the way, using Mike A's recommended drill partway through (until the pilot bores through) and then flip method.

Best blend of inexpensive and effective with best result that one can achieve.

Metal is a different animal.
