22mm (7/8")/25mm (1") Impact Wrenches with Brushless Motor
- "Smallest & Lightest in its class"*1 and "Robust and Highly Durable"
design is achieved by the industry-first*2 AC Brushless Motor + Aluminium Housing Body
*1 As of November 2014. Among 22/25mm-class impact wrenches made by leading power tool manufacturers. (surveyed by Koki Holdings.)

The product life cycle is significantly extended by eliminating troubles with armature burnout, layer short or commutator wear in severe environments. No carbon brush replacement is required.
- Stable performance provided even at voltage drops
Power supply and load conditions are continually monitored to provide stable torque even with an extension cord used.
Tightening torque decrease rate
Test condition: When using 100m extension cord (50m x 2) with 2.0mm2 nominal cross-sectional area of conductor.
(This test condition is just for explanation about the difference of the tools. Please use an appropriate extension cord.)
- Compatible with engine generators
Thanks to Our original, compact & high efficiency inverter circuit.
- Aluminium Housing Body
- Durability remarkably improved
by the internal double-insulation construction with an aluminium die-cast body which firmly holds the rotor shaft, and a plastic stator holder.
: Protects the hammer case.
: Protects the housing.
Reduces slippage and fits comfortably in the hand.
- New trigger
- Tumbler-type forward/reverse switch
Allows quick switching between forward and reverse modes.
Designed to be hung on a rope and a wire. (For WR25SE)
