Hitachi G18DBAL/JJ 18v Brushless Angle Grinder inc 2x 5.0Ah Batteries, Charger and Carry Case The latest angle grinder released by Hitachi including their new feature, \"Auto Mode\". Auto mode conserves energy by reducing rpm in standard operation, as load increases the rpm will automatically increase for greater efficiency. Brushless motors are 30% more efficient than conventional models as no energy is wasted through brush friction thus extending battery run time. They also generate more power providing higher torque levels and workload capacities. Includes a non-lockable paddle switch which improves user safety, commonly known as a “Deadman Safety Switch”. FEATURES High performance angle grinder with high efficiency brushless motor Powerful motor with over-current protection to prevent burnout Kickback protection system, anti-restart protection and soft start provide greater operator safety \"Auto Mode\" reduces no-load noise and vibration Resin coated components and mesh filters for extra protection against dust and moisture Compact body and small grip circumference Large two stage paddle switch (dead man action) SPECIFICATION Voltage: 18v Battery Capacity: 5.0Ah Li-Ion Charge Time: 75 Mins Wheel Diameter: 115mm No Load Speed (Normal Mode): 9000/min No Load Speed (Auto Mode): 5500/min Arbor: 22mm Spindle Thread: M14 x 2 Overall Length: 326mm Weight: 2.4kg
