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!
