Aluminum Killers with 5/16th in diameter steel shafts, these tools are perfect for working on aluminum. The set includes 12", 18", 24" length for both  right and left angles. It also includes 1-36" and 1-48" straight rods. These shafts are shaved for over the brace access.  The outer edge of the kick (blade) is sharp to penetrate glue.   (Note: The set's 24" left and rights have evolved into an F150 pick-up aluminum hood "specialty" tool throughout the PDR industry) All AK16 can be purchased individually.
