5-1. Selling Point Descriptions

Common selling points (Models WH 12DAF2 and WR 12DAF2)
(1) Soft-grip handle
The grip is soft, slip-resistant and comfortable thanks to the soft resin (elastomer) covered on the handle.
(2) Convenient belt hook with LED job light
It can be used as a hook for suspending from a waist belt or storing. Its yellow LED light is very convenient for
such operations as tightening screws in a dark place. This hook features the following:
It can be slid out when necessary and slid in when not necessary with one-touch simple operation. The
angle can be adjusted in 5 steps.
It can be installed on either right or left side. It is easily replaceable with a flat-blade screwdriver or a coin.
The yellow LED light can be lit by turning on its switch when necessary. The lighting direction is diagonal to
minimize shadowing over the tool tip and the operator's hand holding a screw. The light will turn off
automatically after 15 minutes if forgotten.
Selling points of the Model WH 12DAF2
(1) Fast tightening speed thanks to the powerful tightening torque (30% faster than the conventional model when
tightening a universal machine screw of 5.3 mm diameter and 120 mm length)
The maximum tightening torque and the tightening speed of the Model WH 12DAF2 are greatly increased in
comparison with the Model WH 12DAF thanks to the increased output of the motor and the large hammer.
