POWER : Makita-built brushless motor delivers 1,950 in.lbs. of Max Torque VERSATILITY : Digitally controlled modes; two T-modes, one assist mode and three forward/reverse auto stop modes SPEED : 4 speed settings (0-1,100/ 0-2,100/ 0-3,200/ 0-3,700 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-4,400 IPM) CONVENIENCE : Additional one-touch 4-speed power selector button under the chuck for added convenience INCLUDES : Tool only (battery and charger not included) About Model The 40V max XGT Brushless Cordless 4-Speed Impact Driver (GDT01Z, tool only) breaks new ground for the most demanding driving applications in wood, masonry and metal. It is powered by a Makita-built brushless motor that delivers 1,950 in.lbs. of Max Torque, outpowering other impact drivers in heavy-load applications. An ultra-smooth variable speed trigger provides optimum control and a one-touch 4-speed power selector button under the chuck allows users to adjust speed easily. Users get up to 50% faster speed with 4 speed settings (0-1,100/ 0-2,100/ 0-3,200/ 0-3,700 RPM & 0-1,100/ 0-2,600/ 0-3,600/ 0-4,400 IPM), when compared to Makitas 18V LXT Brushless Cordless 4-Speed Impact Driver (XDT16). The GDT01Z offers 9 modes for a wide variety of applications, including two tightening modes, one assist mode, three forward and three reverse auto-stop modes. The two Tightening Modes (T-mode) provide faster tightening of self-drilling screws in thick or thin gauge metal, which helps prevent damage to the screw or workpiece. Assist Mode (A-mode) feature helps eliminate screw cam-out and cross threading by driving at low speed until tightening begins. Three forward and three reverse Auto-Stop Modes provide increased efficiency. This impact driver is a workhorse tool engineered to outlast with Extreme Protection Technology (XPT) to provide increased dust and water resistance in harsh jobsite conditions. Reinforced gear housing provides additional durability on the job site. XGT is a system of equipment, tools, batteries and chargers utilizing 40v max lithium-ion batteries. XGT is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site. XGT is equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability features to outpower, outsmart and outlast the rest.
