Stanley SBW920M2K-B1 20V Bl Impact Wrench

The Stanley SBW920M2K-B1 is a V20 cordless impact wrench with a brushless motor that Stanley says improves power efficiency and runtime. It delivers up to 370 Nm of torque and 3,100 impacts per minute for nut setting and other high-torque jobs, with a 2-speed gearbox (0-900 and 0-1,900 rpm). A 1/2-inch hog ring anvil makes socket changes easy, an integral LED lights the work area and a built-in gauge shows the battery charge. Stanley lists an 18V lithium-ion 4.0Ah battery, a 90-minute charge time and a tool weight of 1.5 kg.
