Ingersoll Rand has just unveiled the new W7150 half-inch high-torque cordless impact tool, calling it "... the greatest advance in cordless technology to date.”

It’s said to perform "shoulder to shoulder" with the company's 2135TiMAX air-powered tool.

Weighing in at 6.8 lb and measuring 9.4 in. from tip to tail, the W7150 features 780 lb ft reverse torque and 1100 lb ft of "nut-busting" torque. It also features a re-engineered rare-earth-magnet motor along with a steel-lined aluminum hammer case and a chemical-resistant, patent-pending, metal-reinforced housing. Its all-metal drivetrain and hammer mechanism mates with a variable-speed switch with electronic brake for optimized control.

The power comes from the company's new IQV20 Series battery platform featuring a strong lithium-ion battery that's said to deliver high charge capacity and low internal impedance for maximum power delivery. The intelligent battery-management system (BMS) provides power-level and flow-rate control from the battery to the switch to the motor, and there's a mountable 'smart' charging station with auxiliary USB port.  The W7150 is the first addition to the new IQV20 Series of 20V lithium-ion cordless tools and will be available beginning in January 2012.
