• Features 4 speed options and 6 assist modes (2 T modes, 1 wood mode, 3 Bolt modes).
• High-performance BL motor (brushless)
• XPT (eXtreme Protection Technology) for increased dust and water resistance during use in harsh conditions.
• Quick-release chuck for easy attachment/removal of accessories
• Constant speed control maintains fastening torque by preventing the reduction of rotational speed caused by decreased battery capacity.
• Variable speed trigger for greater precision across a wide range of applications
• Dual LED work light: for safe operation in low-light areas
• Version Z: body only (without batteries & charger)

The advantage that brushless motors have over brushed ones is that they do not have friction since there are no carbon brushes. Without carbon brushes, the motors are more efficient and have a longer lifespan as there is no wear and tear (the carbon brushes in brushed motors wear out with use). They produce less noise, maintain their torque consistently at all speeds, do not overheat, and require no maintenance.
