5-1. Selling Point Descriptions
Common selling points (Models WH 12DM and WR 12DM)
(1) New, compact and cyber design
The Models WH 12DM/WR 12DM have vibrant and cyber looks thanks to the widely adopted soft urethane
resin (elastomer) and the complicated 3-D curved surfaces, stirring up curiosity to touch them.
The Models WH 12DM/WR 12DM are equipped with a separate-type motor in which the armature is
separated from the magnet like a 100-V motor while the previous models are equipped with an integrated-
type motor contained in a steel case. Thanks to the new separate-type motor, the steel case is eliminated
and the motor section is downsized. In addition, the hammer case is downsized. The overall length of the
Models WH 12DM/WR 12DM is shortened by 9 mm, the girth is shortened by 10 mm and the height is
shortened by 19 mm in comparison with the previous models as shown below. The Models WH 12DM/
WR 12DM are convenient for working in narrow places.
The weight of the Models WH 12DM/WR 12DM is heavier than C by about 80 g because they are equipped
with the hook, and the gears and the motor are strengthened to enhance the durability and the
performance.
The Models WH 12DM/WR 12DM are easy to handle and well balanced thanks to the change of the handle
angle from 5˚ to 10˚ to cope with the user demand (C: 15˚). This is the optimum angle determined in the
factory by making sample machines.
(2) High durability
Owing to the shift of demand from nails to screws and increased demand for long screws, impact drivers
having high heat resistance in continuous operation are much sought after. However, there are problems such
as heavy noise or vibration of the ball bearings and decrease in power if the impact drivers are used harshly in
dusty environments. In addition, higher strength and longer service life are required to continuously tighten
and loosen bolts in scaffolding and demolishing works. The Models WH 12DM/WR 12DM have high durability,
dust resistance and long service life in continuous operation as described below.
