Hitachi WR22SE 3/4" Impact Wrench (Replaces WR22SA)

Features

• Ultra efficient AC Brushless motor  that permits the use of extra-long extension cords without power loss, extends product life and eliminates maintenance of armatures or carbon brushes
• Superior performance when using a generator due to an internal inverter circuit that regulates uneven power supply
• AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool. Externally, the metal body construction is more resistant to jobsite impacts and harsh conditions than plastic counterparts. Internally, incorporating a plastic stator holder around the Brushless motor provides the internal double insulation construction that can protect the user from electric shock. The motor and hammer bearings are seated in the metal housing to reduce vibration and stress, and increase stability. During use, the metal keeps the internal gears secure and aligned preventing wear and power loss, Additionally, the metal body dissipates heat better, increasing overall motor life
• 8.3 Amp (800 Watt) motor produces an amazing 460 ft-lbs of tightening torque to tackle the toughest jobs with ease
• Delivers a no-load speed of 1,400 RPM, an impact rate of 2,000 IPM
• A/C or D/C, can be used with a DC power source
• Soft start ramps up gradually for more control
• Electric brake stops the rotation within seconds to prevent over tightening     
• Large heat-resistant bumper protects the tool, workpiece and the user
• Forward/Reverse toggle switch to quickly change fastening direction
• 360 Degree adjustable/removable side handle for optimal comfort and control
• Soft, non-slip elastomer grip handle for improved comfort and control
