A best bet is the DEWALT 18-volt Cordless Compact Hammer Drill/Driver (pictured), model no. DC725KA, for $140.99 with free shipping. That's the lowest total price we could find by $63. This 4.8-lb. drill features a 0.5" single-sleeve ratcheting chuck, dual-speed range of 0-500/0-1,700 rpm 0-8,500/0-29,000 bpm, LED worklight, and more.
