I want to get a new set of drill bits. I hear that cobalt is a better bit than titantium coated. I'm not looking for high end machine shop quality, but i don't want junk either. I drill metal and plastic at times.

Carbide tipped works well all around.
I've tried a bunch of different drill bits for my work. It includes a little bit of machine shop work on aluminum, steel, and stainless steel, plus lots of field work drilling mild steel and aluminum.
The "home store" drill bit sets are okay, though their TiN coated sets are not great compared to real industrial drills.
Here's an uncoated cobalt set I've been using for a few years. It's pretty good:

Cobalt M42 (8% cobalt) bits are the ones to get not the M35 (5%).
This is a decent set for not much $ for what you get. AFAIK Cleveland drill bits are still USA made.

That's just it, unless they're machine shop quality, they never work for me; they literally do not cut steel. The only time I can get by with Lowes quality is if I'm going into wood.

Those are wire size 1-60, make sure you get the set that meets your needs. Inch, metric or wire.
This is a larger size inch set. I like to have a set of small and large but if was going to use just one it would be this or a metric set.
The price is good on these drills.

Agreed, you want the M42 cobalt bits. Cleveland is a good brand and still made in USA, however, a few years back they were sold and are now owned by a Chinese parent company.

Cobalt is preferred but TiN coated HSS should work, however some stainless can work-harden if you're not pulling a chip and just rubbing. I suppose the forming process of making the flashlight could work-harden it as well. Be sure to use sharp tools and feed it enough to cut a chip.

While on this subject, what is the proper cutting oil to use? I have used mmo, but i don't know what is in a true cutting oil.
I use tap magic. Good for tapping and drilling in steel. CRC has some as do many others, its a common fluid.
Kerosene and lard or bacon grease work well too, ATF and a little kerosene or straight Kerosene for aluminum an brass. Lots of others.
MMO, WD40 and so on, not really.

I have the following set and it has held up better than others I have bought.

Its cheap, but I lose drill bits before they wear out.
