Makita XDT16T 18V LXT Lithium-Ion Brushless Cordless Quick-Shift Mode 4-Speed Impact Driver Kit (5.0Ah)

Quick-shift mode use the electrical controls of the brushless motor to determine the ideal balance of speed and torque for each application, resulting in more efficient fastening. The BL Brushless motor has a maximum RPM of 3,600 and a maximum torque of 1,600 lb. The 4-speed power option (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) allows for fine fastening control in a variety of applications. For extra convenience, a one-touch 4-speed power selector button is located beneath the chuck. By operating at a low speed until tightening begins, the assist mode (a-mode) function helps minimize "screw cam-out" and "cross threading." Product Dimensions (cm): 15.24 x 43.18 x 33.02   Makita has a long history of innovation in the cordless impact driver sector, and the 18V LXT Brushless 4-Speed Impact Driver (XDT16T) continues that tradition. The XDT16T has four speeds and Makita's proprietary Quick-Shift Mode for more fastening control. Quick-Shift Mode uses the brushless motor's electronic controls to determine the ideal speed and torque balance for each application, resulting in more efficient fastening.
