Milwaukee delivers huge value with this bundle, providing a charger, case and two lithium-ion batteries for slightly more than you would pay for the tool alone. The M12 3/8 in. hammer drill/driver is the only tool in its class with an all-metal chuck, one of the reasons professionals turn to Milwaukee for durable equipment. This 12V lithium-ion subcompact supplies up to 275 inch lbs. of torque and features a ratcheting chuck to ensure bits stay securely fastened under ever-increasing loads. Choose between two speed settings (0-400 or 0-1500 RPM) and one of 18 clutch positions for optimal torque. The contoured handle enables firm command and control while the responsive variable-speed trigger reacts quickly to user actions.
