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.

Is the Gold just aesthetic? Assuming so since gold is pretty soft.
These are just black oxide bits with some "gold" coloring to make them look attractive. The "gold" really doesn't do anything except maybe prevent some rusting, though rusting drill bits really isn't much of a problem if you actually use them.

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.

Carbon Steel

Titanium

Knowing SD, people will debate the order a little bit. Regardless, HSS will dull while drilling through any material faster than Carbide.
