Unibit size for enclosure drilling

[p00n]

Like for holes for pots, LEDs, jacks etc.

 

Which sizes do you use? Best if you know the model numbers.

 

 

Thanks in advance people

The smallest one that goes from 1/8" to 1/2" is perfect. The largest holes are for the 3PDT switches and dc jacks. They're 1/2". For all other holes, the exact sizes are represented.

I use the #1 which goes from 1/8" to 1/2"
These things and a drill press make drilling a hassle free experience

I want a drill press .

Thanks guys!

 

I'd love a press too but I'll probably try to wing it with a cordless drill. Should I invest in a punch and a thin bit for some guide holes? Or just go all ghetto on it's ass with a nail and a hammer to make an indentation?

why not just buy the proper size bits, and a 1/16 or 1/8 for pilot holes.
those uni bits are for the Home Depot crowd aren't they?

It is more convenient, less changing bits etc. I think it works out to be cheaper than getting a whole set

you don't have to buy a set, you can buy quality individual bits at good tool suppliers. the same bit will do pots and jacks, I think it's 5/16, I'm going on memory and could be wrong. you probably only need 3-4 bits, and it might be easy to use individual bits sans drill press. just a thought.

Unibits debur too.

 

I've tried both regular bits and the unibits. Unibit is WAY better. More circular, smoother holes.

Harbor Freight. Got a set of three for less than $10 on sale. Much cheaper than buying the brand name, and seem to work fine. Not going to hold up to regular hard usage....but how hard are you going to work it???

Get a used drill press for $40. It's $$ well-spent.

I measured all the offboard components I use with some digital calipers so I could get the hole sizes as close as possible, and this is the list:

 

 

Part Actual Bit

Alpha Potentiometers 6.78mm 5/16"

9V DC (non switched) 7.78mm 8mm

9V DC (switched) 11.7mm 12mm

1/4" Sockets 8.76mm 3/8"

3PDT Footswitch 11.7mm 12mm

LED (3mm with metal bezel) 5.56mm 6mm

I've got 1 metric and 1 imperial step drill bit that covers everything.

That's great--thanks!

You'll never go back!
