Skil Power Tools. Lighter and more compact than comparable 18-volt NiCad tools, the 18-volt lithium ion product line includes a 1/2-inch two-speed drill/driver; a drill/driver and 53/8-inch SkilSaw combo kit; a drill/driver and reciprocating saw combo kit; a four-piece combo kit including all three tools and a pivoting-head flashlight. Users can upgrade their Skil NiCad tools to the more efficient Li-ion system by purchasing just the 18-volt battery and charger. The new batteries give owners a lighter tool and more consistent power throughout the cycle, and last up to four times longer than NiCad batteries. 877.754.5999. www.skiltools.com.
