How to make holes in plastic boxes?

[OM2]

Thanks for the replies guys.
Hot rod I would consider something similar like a soldering iron.
But would prefer drilling
The drill I uses was a wooden drill bit. If I used another type, maybe would be better?
Adding wood sounds perfect - but then how do I do the same job again 100 times?

100% this

if you have loads make up 2 jigs
the face board needs to be deeper than the amount the drill point is protruding although once the wooden face discs have been cut out and removed from the face jig you dont need a auger/drill bit at all for holes sticking forward so can be cut short /retracted or removed dependent on design
this board can be cut to fit snugly between those ribs and the lip at the top
the inner one will be probably fitted to the width and base probably with shaped edges to locate accurately
you then with a solo clamp away from the drill area clamp them firmly together
the first 4 holes in situ will make the jigs complete as in the outer jig plate will now have a cut hole with a auger/drill hole on the inner plate
once set up you will only have to empty the hole saw off plastic discs every few boxes at the point the cutting teeth have less than 5mm behind them full off plastic

Any chance of a video?
Really complex and hard to follow
Thanks

get a board of 18mm ply

cut it to fit inside the box, so it goes down to bottom -chamfer edge as needed, put it in place, then screw a batten on the ply so it sits against the top of the box lip

then take out the ply, drill 4 holes (size of centre drill in hole saw to match the position of the centre of the holes

then drill the holes


the problem you have at the moment is when you drill in the centre drill makes the hole bigger so there is no centre guide for the drill and it wobbles
