What are these drill bits?




I have a "Hi-Spec Cordless 3.6V Screwdriver & 102 Piece Insert Bit Set" - butI can't seem to find information on what the heck all of these drill bits are used for.(I found websites but they dont explain the pieces. I got my set from Amazon)Now there are some that I know what they are :) But there are some odd looking ones.What are these for?Thank you!

Most of these bits you will never use. On occasion you will find an odd shaped screw and you will definitely have the bit to fit it. This many are not usually used by a home owner.
I see several on there that are used for very specific screws that you use on only one type of job, like siding. Most of the time if you buy those type screws it comes with a bit but I would hang on to them, just in case.
They are to remove or put screws in. There is star bits, straight bits Phillips bits, square bits among several others. That’s. Great set.
Thank you everyone so much!!!
They work with different screws. For instance, star bits work with deck screws.
A number of those screwdrivers are used for screws in RVs as they use quite a number of stars or Square screwheads. Carolyn, full time RV'er
I'm late with my answer but I agree, you won't be using most of those. Besides they look cheap and won't last long in my opinion.
