All drill bits can be resharpened. There are a bunch of jig tutorials on youtube. I have a lifetime supply of drill bits from the guy use to work for. He would use them for a couple times then chunk them when they got the slightest bit dull. I told him they can be resharpened in a couple seconds with a low speed grinder. He said it wasn't worth his time so they became my drill bits. It takes about 15 seconds per bit to sharpen. Just line them up and sharpen all your semi-dull bits at one time. You can do about 20 bits in 5 minutes and you're done. FYI you can also sharpen Unibits in about 2 minutes. He also chunked those.

it will fit any brand drill as long as the chuck is big enough (which I'm sure it would be)
You think that guy knows what a chuck is?

Yes, you can resharpen most bits, however once the special coating is gone you lose it's advantages and are just left with the base metal which is often relatively unimpressive on these coated bits.
Almost all halfway decent drill bits use a base metal of high speed steel. They are then coated in Titanium or cobalt in a process similar to electroplating. You still have the base metal underneath. If you keep a bit cool, meaning too slow is better than too fast, will keep the bit edge sharper far longer. Whether you're drilling steel, wood, plastic, or concrete, slower is ALWAYS better. I've seen may people use a drill bit to the point it's burning the material, hence the smoke. I have a 1.5" wide drill bit thats about 6" long. It started out about 12" long. I cannot tell you how many times it's been resharpened probably 100ish or so. Better than buying a $40 bit each time. You can always drill for a few seconds and then do something else for a few minutes, then come back to it after it has cooled.

Not even close.

Carbon Steel
High-Speed Steel
Titanium
Cobalt
Carbide

Knowing SD, people will debate the order a little bit. Regardless, HSS will dull while drilling through any material faster than Carbide.
That ranking is more or less accurate, but in my experience titanium doesn't always get you much advantage over just HSS.
Titanium drills have a titanium coating on HSS, and other factors seem more important (design, geometry, quality control). Black oxide provides rust resistance to HSS and apparently lessens friction.

Cobalt isn't just a coating, but a steel alloy that includes typically 5-8% cobalt, and can deal with harder materials. Carbide drills can deal with the hardest materials and most of these are carbide tips on some type of steel drill to reduce cost.

Cobalt isn't used as a coating, but it is added to the alloy which increases hardness.

This is true I meant black oxide. Cobalt bits are bits that have cobalt is added during the manufacturing process at roughly 5-8%.

I was just considering these but went with another instead. Will I regret my decision?

Generally speaking, M35 Cobalt is going to beat the pants off of black oxide high speed steel, however I would have serious reservations regarding one of those ALL CAPS Amazon only brands and that's a pretty small set maxing out at only 1/4".
