Industry first high performance 800W Brushless motor – providing smaller more lightweight tool – only 4.6kg
Unique Maintenance-free Brushless motor provides significantly longer life
No carbon brush replacement required
None of the traditional problems from conventional brushed commutator motors
Stable Performance under voltage drop situations
Unlike conventional electric Impact Wrenches, output torque isn’t affected as much by voltage drops from long extension leads on site.
Example: 100mm extension load, 2.0mm² conductor. Performance of conventional models drop by approximately 21%, new HiKOKI Brushless models decrease by just 7%.
Stable Performance when used with Generators
HiKOKI’s Brushless design operates consistently and without the traditional problems cause by generator use.
Requires suitably sized Generator output.
High performance 620Nm tightening torque
Aluminium Housing Body (AHB) provides a super strong aluminium die-cast body with internal double-insulation making the housing more rigid, significantly enhancing durability of the motor unit.
Front and rear rubber bumpers to protect tool and work material
Rocker switch provides quick switching between forward and reverse
