How do I get the Powered Drill?

You can get the Powered Drill by merging the Pencil up to Level 10, which is the Powerless Drill. Adding one Rechargeable Battery to the Powerless Drill will turn it into a Powered Drill.

Make sure the item you want is actually the Powered Drill. For that, tap on the information button above the item in your task to check. Be mindful that the powered drill cannot be split or merged into the other items of the workbench chain.
