With the Drillin' Action Tool Set, little ones can screw the wood pieces together with their very own drill that actually works. This lean, mean, drilling machine works in forward and reverse, makes realistic drilling sounds, and comes with three interchangeable drill bits so preschoolers can choose the right one for the job. Everything stores easily within the toolbox, making cleanup a breeze. While your little DIY-ers build and repair, they develop fine-motor skills by lining up screws with the holes and drilling the screws. Matching up the right drill bits with the right screws and discovering how the drill works to attach the pieces of wood together helps them learn early engineering skills. Pretending to build or repair stuff helps preschoolers build their imagination in a big way. Plastic tool set is recommended for children ages 2 to 6 years.
