Why it's hot: Because five heads are better than one

Oscillating multi-tools, with their variety of attachments, already provide you with a lot of versatility. The 12-volt JobMax from Ridgid, however, goes even further with its range of tasks, making it a super-multi-tool. You can swap out the oscillating-tool head for a right-angle impact driver head, a right-angle drill head, a ratchet head and an auto-hammer head. That’s a lot of jobs.
