5-1. Selling Point Descriptions

(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.
(3) Increased tightening torque thanks to the powerful motor (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 of the Model WH 14DAF2 is greatly increased in comparison with the Model
WH 12DAF2 thanks to the increased output of the motor.
Comparison of number of screws tightened
Figure 1 shows the number of wood screws (5.3 mm dia. x 120 mm length) tightened into lauan workpieces.

* The number of screws tightened may vary depending on hardness of the workpiece, ambient
temperature, characteristics of the battery, etc.
(4) Max. torque 120 N

The maximum torque is 120 N
mechanical strength with the durable die-casting aluminum hammer case, etc.
Tightening torque comparison
Figure 2 shows the torque required for
tightening an M14 high-strength tension
bolt in 3 seconds with a hexagon socket
(overall length 33 mm) (9% higher than
the Model WH 12DAF2).
*1: Max. tightening torque is based on tightening an M12 high-strength tension bolt in 3 seconds with a
hexagon socket (40 mm long).
