4-1. Selling Point Descriptions
(1) Class-top tightening torque
With the powerful motor and the computer analysis for optimum impact at tightening, the tightening
torque of the Model WR 22SA is 610 N•m, which is the highest level in this class.
(2) More durable double-insulated motor thanks to the highly strong (rigid) aluminum die-cast body
The motor is contained in the highly rigid aluminum die-cast body and the handle-integrated plastic
cylinder doubly for higher rigidity of the housing. Thanks to this double-insulation structure, the
durability of the motor is remarkably increased. In addition, the rear portion of the main body is covered
with resin tail cover for higher durability. The resin tail cover also prevents the CB cap from loosening.
