In an attempt to expand my tool collection, I just purchased a
228-piece drill & screwdriver bit set. The set came with no information on the bits, so, being a novice, I have plenty of questions:=B7 In addition to standard wood and masonry drill bits, the set included "H.S.S." drill bits with both Titanium coating and bits with black oxide coating. When would I use these over the standard bits, and when would I use one over the other? And what does "H.S.S." stand for?
=B7 The set includes three plastic "screw finders." How are these used?
=B7 The set includes both a "Quick Changer" and a "Bit Holder" which appear to do the same job, allowing you to pop bits in without dealing with the chuck. Is there a difference between the two?
=B7 And for Pete's sake, it takes an act of God to get any of the pieces in or out of their molded plastic slot in the case. Is there a trick to removing/replacing them?
Many thanks.
