What drill bit for a cable hole in lacquered wood?
 
I need to drill a circular or semi-circular hole in a plank of wood that's 0.75in thick "engineered wood" and has a coat of white lacquer. Here's a photo. It would be on the base of it.

The hole would need to be big enough for a grounded power plug. What's the best drill bit to use for something like that? Spade, hole saw...? Any other tips?

Is the bottom going to be showing?
If so then only drill 1/2 way through from both sides with a hole saw.
Just take your time when it's starting so there's no tear out. Once it's through the top surface let it rip.
Really should have been drilled before assembly.

measure the plug and then use a paddle bit -drilling from the exposed side that you will see later, let any blowout happen in the back...

I would use a hole saw.....and make the hole big enough for one of these.....

Visit Rockler.com for more examples....

And I wouldn't use a paddle bit on that wood....one large enough is going to mess it up.

A paddle bit (Spade bit) is not the correct way to do this. The front of the hole will be rough and the back will be a disaster exhibition point

i like the ddawg16 recommendation but when drilling with hole saw or forstner bit place a block of wood tight against other side where drill bit will be coming out this will prevent blow out

if done with enough rpm it will be fine. It is one of the many materials I've drilled through with a paddle bit, work it easy and slow with enough rpm and wa la but for the inexperienced you could be right.
