How to make holes in plastic boxes?

[OM2]

Well the drill must have been 8mm I guess... I had to nudge around while drilling to make the hole bigger.
That's why it looks a big mess in the holes

Lots of cable tidies already exist and a lot smarter looking and convenient than an ugly plastic box full of holes.
Doubtful you could give those away .

Harsh! But fair.

OK so no one else has asked, why the hell are you using that type of plastic box for electrical connections?
They have an absolutly zero fire rating, proper boxes have self extinguishing additives to ensure the box does not set on fire.
I hope to god that your not charging anyone for this lash up, the insurance company will have a hissy fit at the use of unsuitable equipment.

If you really have to be a cheapskate, then I'd go for the stepped drill option myself, and use nylon glands rather than leave gaping holes for little creatures to crawl into (and cause a fire when they make a nest).

only 8mm ??? i thought they where large boxes and the holes where perhaps 35mm
so clamping wont work
sorry about any confusion i may have caused

It's the usual no context thread isn't it, any useful information has to be extracted rather than being forthcoming.

No, the wooden drill bit is one of these:

I'm guessing this is what caused the plastic to get mangled up as shown in my original pic and why I didn't get a cleaner hole.

I'm trying to make a cable tidy box for mobile phones.
I want to just add something in the middle from charger to phone so I reduce the big tangle of wires.

I thought it would be a great item to sell.
Buy small plastic boxes and drill holes in.
Super useful I think.
