The Makita TW008GZ 40V XGT Brushless Impact Wrench from ITS is a versatile and powerful wrench with ½” square connection with spring locking pin. The impact wrench, with a maximum 760Nm fastening torque, has four adjustable impact power selection for adjusting the torque to the work piece. The Trigger switch with full speed mode means that Variable speed mode can be changed to full speed mode simply by pushing a button. Because in full speed mode the trigger travel is shorter, the full speed is reached faster. Equally, the TW007 also features an Auto stop mode when reversing. The tool stops automatically as soon as the bolt or nut has been loosened sufficiently or can continue to run at low speed. Also included within the Impact Wrench is an electric brake, variable speed control, twin LED job lights as well as being compact, well balanced making it comfortable and easy to handle in difficult places. At the heart of this is the brushless motor that allows you to use it efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it. (There only difference between the TW007 and TW008 is that the TW007 is equipped with ½” square connection with friction ring and hole for locking pin).
