HIGH-TORQUE MOTOR : Delivers up to 1,180 Ft.-Lbs. of fastening torque and 1,620 Ft.-Lbs. of max breakaway torque PROFACTOR PERFORMANCE : Delivers high torque for breaking free stuck bolts and tightening large fasteners quickly BITURBO BRUSHLESS TECHNOLOGY : Featuring a brushless high-performance motor and drive-train system engineered to take full advantage of the additional power generated by CORE18V High Power batteries (sold separately) THREE SPEED/TORQUE SETTINGS : For greater control over power output (0-800 / 1,300 / 1,750 rpm) FRICTION RING AND THRU-HOLE : Allows for fast socket changes and a more secure fit AUTO SLOW DOWN : Slows down rpms when fastener head is close to the workpiece for controlled driving AUTO STOP : Shuts the tool off when screw head is flush with the workpiece to help prevent overdriving makes repetitive driving easier and more consistent AUTO BOLT RELEASE : Stops rotation when there is no load on the tool to help prevent accidentally dropping bolts and nuts during removal ONBOARD USER INTERFACE : Provides speed-setting control and tool-status feedback REMOVABLE RUBBER BOOT : Helps to protect the head of the tool and work surface
