Are SDS drill bits the best idea ever?

Greg told me to purchase a SDS drill and I purchased this DeWalt D25313K Heavy-Duty 1 inch SDS L-Shape 3 Mode Hammer.  I love these SDS drill bits and I guess the drill and my cheap Harbor Freight drill bits ($10 a piece, 42639, 42651 Drill Master masonry bits) are good.  Why does every drill bit not use this system.  The second picture shows the SDS bit layout, it consists of a locking mechanism.  The third picture shows the chuck, which you just jam the drill bit in and it clicks in place.  The fourth picture shows how you remove the bit by just pulling the chuck back.  This system is just for masonry bits I guess, but why?

I did actually use the drill and I mounted and reinforced some stuff.  The last picture is all the crap I needed to install a couple screws.

  1. The best thing about having a good masonry drill is that with casual use you’ll never wear it out. I used to go through a cheap one every year, but I’ve had my Porter Cable SDS for 10 years now and it works as well as it did when it was new.
