Right off the bat, I would say a 30º hole would be below freezing unless you are using the Centigrade scale.
A lot of drill presses have adjustable tables so you can loosen the bolt and then tilt the table.
Another approach is to use an angle vice. Harbor Freight has one for about ~$30 which is pretty neat.
And then there is the radial arm drill press -- but you already have a DP.
Finally, you could make a jig.

Only 20 degrees here this morning. Would have to wait until later in the day.
If you mean 30 degrees relative to the surface then that's a pretty oblique angle. You pretty much need a jig or some sort of solid clamp to hold things rigid, and you'll need to feed slowly until the hole's started, so that the bit doesn't flex off to one side or the workpiece flex off to the other side.
A regular multipurpose or HSS bit should work in most cases, if you feed slowly. You wouldn't want a really pointy bit like one ground for aluminum, and the bit needs to be pretty sharp on the corners if you're drilling something hard. If it's hard steel you're probably best advised to make a starting pit by drilling perpendicular to the surface first.
What are you drilling into? Wood? Metal?
Most if not all drill press tables will tilt to 90 degrees (parallel with the quill). For an angle that steep, though, if possible, I'd clamp some sacrificial material to the piece for the bit to enter first. This block will support the bit as it enters the workpiece and will also prevent chipping.
What diameter is the hole? I've used the tapered-point drills like this:

when drilling steep angles. Other types of bits may want to catch and wander because the edge will hit before the point. Critical to this is a good jig to hold the work piece, whether or not you tilt the table.
Just drill 2 @ 15.

I agree with OverKnight. He's got his lance in the right place. Clap, tilt then drill. One change though, I'd advance the scrap block to cover your center mark if you working with tolerances of less than 1/8". In other words, the upside of the pencil mark where the bit enters. And if its really critical to hit dead center, drill a pilot hole with a smaller diameter bit just enough to judge if you're where you want to be. I've done a little Pattern-making in my day. And have run into weirder drilling situations than that.
Best to you and yours, Chris.
Some say I know too much.
It should be noted that on a deep hole in a flat surface one is likely to have trouble with the chuck interfering with the workpiece. If a relatively small bit is being used, the best solution is to chuck a smaller chuck into the press chuck. Simply using a longer bit will greatly increase bit deflection, and using a bit extension will cause unmanageable wobble.

He never said how much reach he had to the hole or how deep.Best to you and yours, Chris.

Right. Was just making the suggestion IN CASE it was a deep hole.

I would screw and glue together a wedge-shaped jig and clamp it to the table. Then I would use a Forstner bit to slowly start the hole. Once the hole is fully into the material, you can switch to a longer regular bit to finish the job. Depending on the size of the bit, you should have no trouble finding a long bit that will handle the steep angle and keep the chuck away from the workpiece.
But what if he ain't drilling wood? Forstners really don't like steel.

I assumed it was wood. For steel, I do not have a clue.
Me either, short of a milling machine and a cutter vs. a drill bit.

If it's wood a forstner bit will do it with no problem.
If it metal, a little more work. One way to do this is to take anothe rpiece of steel with the opposing angle and clamp them together. this wall then form a restangle and you can the drill through the one and into the other. Once you get though the first one, remove it and then continue going through the other.
Brownbagg, you've read all these messages, why don't you respond to some of the questions?
'cuz it's BrownBagg.
He's drilling concrete, y'all are talking about steel and wood.

Much easier to drill half a hole at 60. Only you gotta decide whether to drill the top half or the bottom half.

Do what? Dril holes or disappear?
I was waiting to hear whether this is in steel or wood to answer...

just wondered how things are going with your project^^^^^^

I think it got down to 30 degrees in his neck of the woods so he's probably "holed" up somewhere waiting for salvation.
its finished, was a great hit, I got about six orders for more.

I guess you don't want to tell us what it is you were making^^^^^^

this is not the right place.
Sounds like my old shop teacher.We would ask him "what are you working on?" and he would say something like " a butt hole for a hobby horse, now get the hill outta here".^^^^^^
