1. PRODUCT NAME
Hitachi 13 mm (1/2") Drill, Models D 13VB3, D 13VH
Hitachi 10 mm (3/8") Drill, Model D 10VJ
2. MARKETING OBJECTIVE
The Models D 13VB3, D 13VH and D 10VJ are upgraded versions of the current Models D 13VB2, D 13T2,
DUT-13, DUT-10 and DU 10. The performance is greatly improved.
These three models are developed under the concept for compact, lightweight and powerful drills. The main
features of the Models D 13VB3, D 13VH and D 10VJ are as follows:
(1) Compact and lightweight
(2) Class-top drilling speed
(3) Powerful motor
(4) Shortest chuck offset
(5) Durable aluminum gear cover and inner cover
(6) Two-finger sized trigger switch with speed control dial
(7) Low noise 79 dB
3. APPLICATIONS
(1) Rotation only function
Drilling into metal, wood and plastics
4. SELLING POINTS

4-1. Selling Point Descriptions
(1) Compact and lightweight design for less user fatigue
To make the Models D 13VB3, D 13VH and D 10VJ compact is the first priority at designing.
Its ease of operation is the class-top level.
(2) Class-top drilling speed
Thanks to the powerful motor (rated power consumption: D 13VB3: 790 W, D 13VH/D 10VJ: 690 W), the
Models D 13VB3, D 13VH and D 10VJ can drill at the class-top speed while it is compact and lightweight.
And powerful motor also provides high performance for heavy-duty applications.
(3) Easy-to-operate 2-finger sized trigger switch with speed control dial
The pulling amount of the trigger can be adjusted on the dial. It is convenient for operation keeping at a
desired speed. The large variable speed control dial and the 2-finger sized trigger switch are easy to operate.
(4) Reliable and convenient push-button type forward/reverse changeover switch
The Models D 13VB3, D 13VH and D 10VJ are equipped with the push-button type forward/reverse
changeover switch that is more convenient and reliable than the lever-type switch. In addition, this switch is
properly shaped and located not to make the push-button an obstacle at drilling.
(5) Durable aluminum die-casting inner cover and gear cover
The Models D 13VB3, D 13VH and D 10VJ are equipped with the aluminum die-casting inner cover and gear
cover for increased durability.
(6) Low operating noise 79 dB
The Models D 13VB3, D 13VH and D 10VJ are so constructed that the motor cooling air is discharged quietly.
Thanks to the new construction, the operating noise level is 79 dB. The Models D 13VB3, D 13VH and
D 10VJ can be used indoors without concern for the operating noise.
(7) Slip clutch mechanism (Only the Model D 13VB3)
The Model D 13VB3 is equipped with the slip clutch mechanism to avoid direct and strong reactive force due
to a sudden and heavy load by slipping the transmission portion between the motor and the drill bit.
