Makita XDT19Z 18V LXT Lithium-Ion Brushless Cordless 4-Speed Impact Driver (Tool Only)Makita has a legacy of innovation in the cordless impact driver category, and the 18V LXT Brushless 4-Speed Impact Driver (XDT19Z) sets new standards. The XDT19 offers 4-speed power selections (0-1,100/ 0-2,100/ 0-3,200/ 0-3,600 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-3,800 IPM) which provides precise fastening control for a wide range of applications.The Impact Driver features Assist Mode (A-mode) which helps eliminate screw cam-out and cross threading by driving at low speed until tightening begins. It also features two Tightening Modes (T-mode) for faster tightening of self-drilling screws in thick or thin gauge metal that helps prevent damage to the screw or workpiece. The XDT19 delivers industry-leading performance in a compact and ergonomic design.Added features include the one-touch 4-speed power selector button under the chuck, which enables one-handed speed changes, and reverse rotation auto-stop mode which stops rotation and impact when the fastener is loosened adequately to help prevent over-loosening and dropped fasteners.Its part of Makitas expanding 18V LXT system, the worlds largest cordless tool system powered by 18V Lithium-Ion batteries. Makita 18V LXT batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.Quick-Shift Mode uses the brushless motors electronic controls to find the best balance of speed and torque for each application for more efficient fasteningMakita-built brushless motor delivers 3,600 Max RPM and 1,590 in.lbs. of Max Torque4-speed power selection (0-1,100/ 0-2,100/ 0-3,200/ 0-3,600 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-3,800 IPM) provides precise fastening control for a wide range of applicationsAdditional one-touch 4-speed power selector button under the chuck for added convenienceAssist Mode (A-mode) feature helps eliminate screw cam-out and cross threading by driving at low speed until tightening beginsTwo Tightening Modes (T-mode) for faster tightening of self-drilling screws in thick or thin gauge metal; helps prevent damage to the screw or workpieceReverse rotation auto-stop mode stops rotation and impact when fastener is loosened adequatelyDesigned with dual ball bearing chuck to reduce bit wobble and run outBuilt-in L.E.D. lights on both sides helps eliminate shadows and illuminate a larger areaCompact and ergonomic design at only 4-1/2 longWeighs only 3.3 lbs. with battery (battery not included) for reduced operator fatigueEfficient brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per chargeThe brushless motor eliminates carbon brushes, enabling the motor to run cooler and more efficiently for longer lifeThe electronically-controlled brushless motor efficiently uses energy to match torque and RPM to the changing demands of the applicationFeatures Extreme Protection Technology (XPT) which is engineered to provide increased dust and water resistance in harsh job site conditionsConvenient one-touch 1/4 hex chuck for quick bit changesAll metal gear housing for increased job site durabilityRubberized soft grip provides increased comfort on the jobDimensionsProduct Depth (in.)0 inProduct Height (in.)0 inProduct Width (in.)4.5 in
