What guy doesn't always needd some new drill bits? From some going missing, burning up or getting dull, or even just breaking, replacements are always needed. And this set has basically every size a home carpenter could need. They have sharp points, the quick change ends work great for battery operated screw guns and drills, and the titanium coating helps them to slide through the wood with ease, helping to prevent breakage. The included storage case is an extra nice touch.
