18V Trimmer Router with Brushless Motor Technology25% more power Brushless motors have fewer moving parts results in a quiet motor that never needs maintenance. The reduced friction enables a better use of available energy from the battery pack as there is no resistance from brushes50% more run time Brushless motor technology means the carbon brush resistance is eliminated, so less battery energy is wasted. The efficiency of a brushless motor results in a greater run time from each chargeVariable speed with soft start for control and consistent application into a variety of materials.Vacuum adaptor included for dust extractionLock on/off switch for added safety.3/8 and Collet suitable for most sizes of router bits Built in LED for improved visibilityErgonomic design for increased user comfort
