Ridgid's Jobmax tool has a single motor-and-battery base designed to power interchangeable, task-specific heads. This kit comes with three heads: a right-angle drill/driver and right-angle impact driver, which fit in places even the smallest compact tool can't, and an auto-ratcheting impact wrench, ideal for tightening bolts under the hood or on a new BBQ set. Additional heads run about $50 apiece.
The kit comes with batteries, charger, bits, and carrying bag.
