Rockwell's 3-pound H3 rotary hammerdrill has an SDS-plus quick chuck that converts it to a three-jaw drill or power screwdriver. The rotary hammer operates at 0 to 4,800 bpm, with a no-load speed of 0 to 900 rpm. Its drilling capacity is 3/8 inch for wood and concrete and 5/16 inch for steel. The 12-volt battery drills up to fifteen 14- 1/4-inch holes in 4,800-psi concrete on a single charge, the company says. The tool includes a 30-minute charger with a built-in USB port and is covered by the maker's Free Batteries for Life program. Price: $179. 866-514-7625. www.rockwelltools.com.
