The XVJ02Z features a brushless motor and has 3 orbital settings plus straight cutting for faster and more accurate cuts in a variety of materials. The variable speed control dial (800-3，500 SPM) enables users to match the speed to the application. In addition， the efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge than similar non-brushless tools. Electronic controls efficiently use battery energy to match the changing demands of the application for increased power and speed when needed. And since there are no carbon brushes， the BL Brushless motor runs cooler and more efficiently for longer life. Convenience features include a tool-less blade change system that allows for faster blade installation and removal， and a large 2-finger variable speed trigger with lock-on button. The heavy-gauge aluminum base is engineered for smooth， accurate cutting and added durability， and the dual LED lights illuminate the work area. It weighs only 5.8 Lb. with battery (sold separately). Tool Only - battery sold separately.
