Thanks for everyone's feedback.
I guess I did mean coating rather than type. I just kept seeing Gold,
Titanium, etc, and I didn't know the difference. Now I understand that
for wood working I do not have pay extra for these type of coatings.
well I'm off to the store
cheers

A drill index is a small "rack" that holds drill bits. It may be a
hinged box, or it may just be a bar with holes in it. A metal index is
a drill index made out of sheet metal (the alternative is plastic)
with a (typically) hinged lid.
Those aren't really types of drill bits - the adjectives refer to
coatings or finishes applied to drill bits. If the bits are for
woodworking, my recommendation would be to not spend extra for any of
them. If they're for metalworking, I'd suggest asking over in
rec.crafts.metalworking
Types of woodworking bits include spade, Forstner, brad-point,
tapered, and standard twist bits. If you browse a catalog sales web
site (like www.leevalley.com), you can see photos and find a bit about
the attributes of each.

I much prefer to buy HSS (High Speed Steel) when it comes to wood working
drill bits.
Today, it is a little hard to buy HSS bits and cutters. Most big Boxes
stores offer mild steel coated with cobalt and titanium.
To learn the difference I made tests with HSS bits from Lee Valley and
titanium coated bits from Busy Bees.
It like day and night. Carbide bits are good for concrete. When buying
router bits quality carbide is superior to HSS.

I would be very surprised if the titanium nitride coated Forstners that
Woodcraft had reduced to 10 bucks a set around Christmas were intended for
use on metal.

The difference in the types of coatings is how hard the surface is and
generally how long the bit will remain sharp. Typically when all types are
brand new you will not see a difference in how they cut.
Additionally these types bits, as Morris has pointed out, are for cutting
metals.
You want wood bits for more precision and cleaner cuts in wood.
