Milwaukee Tool's M12 FUEL 1/4" hex impact driver, No. 2453-20/22, can deliver 18 V performance in a compact, 12 V size with longer motor life, more runtime and a proprietary 2-mode drive control feature. The tool provides maximum torque of 2,650 RPM, but its motor runs quietly. The user can choose between two fastening modes with the drive control feature. Precision work uses Mode #1 and maximum performance can be reached by using Mode #2. Can operate in temperatures as low as -18 degrees F.
