Children love using Design & Drill to create their very own designs or to follow the included patterns to make specific pictures. Just snap any one of the drill bits into the power screwdriver handle, grab a handful of big bolts, and power up the creative fun! This extra screwdriver can be used with the Design & Drill® Activity Center (4112), Design & Drill® Power Tool Workshop (4115), and Design & Drill® Take-Along Toolkit (4117)
