Any good sources for decent/cheap milling bits for a drill press? Looking for an end mill for my JET DP.

Do keep in mind that a normal DP isn't designed for lateral loads...

Looking only to do some light stuff and only the vertical end-mill. Shouldn't have any more lateral/torque loading than a large forstner!

I've used a 1/2" end mill in my OLD (1952) Craftsman DP with good results. Check out Grizzley for good prices on tooling.
Slow the speed, and use a lube. Light oil or kerosene.

Also check with Enco (http://www.use-enco.com/CGI/INSRHM), they are very competitive with pricing.

If you don't have an existing hole, make sure you have a center cut (plunge type) end mill.;) They will cost more than regular end mill.

Something to remember is that end mills are case hardened, shank included. If you hit any tough spots it is easy to spin the mill in a standard chuck. This can RUIN chuck jaws. If you spin a drill bit the soft shank gets torn up but the chuck is ok. Be very careful. Generally I recomend against using a end mill in any drill chuck. The jaws can be ruined and then none of your drills will run true.

Bill, interesting point. Perhaps a second, reasonably priced, chuck to dedicate for the purpose might be a good idea?

Most drill chucks are the jacobs taper type and lateral force will knock it out. So you risk having a spinning endmill in your lap or feet. Putting red loctite on the taper will hold it on for such operations. Some drill presses such as the older craftsman had a threaded collar to hold the chuck on so that would be a safer way to go. You should look at the smaller benchtop Grizzly pin router as a viable option or the Grizzly G0540.
