1. PRODUCT NAME

Hitachi 18 V Cordless Impact Driver Drill/Cordless Hammer Drill, Model DV 18DL

Hitachi 14.4 V Cordless Impact Driver Drill/Cordless Hammer Drill, Model DV 14DL

2. MARKETING OBJECTIVE

The Models DV 18DL and DV 14DL are the excellent, top-quality cordless impact driver drills developed to

reinforce our 18-V and 14.4-V product lines and also to meet the market demands. Each of these models is

equipped with a lithium-ion battery. The Model DV 18DL is compact and lightweight thanks to the new cyber

design. The overall length is 250 mm and the weight is 2.2 kg. While the Model DV 18DL is 3 mm shorter and

0.4 kg lighter than the conventional Model DV 18DMR, it provides the class-top maximum torque 64 N

m thanks to

the optimally designed motor and mechanical unit. Features of the Models DV 18DL and DV 14DL include the

following:

Powerful motor equipped with a large radial fan

Sturdy metal chuck and metal clutch cap

Selectable rotation speed in four steps with the shift knob and the change lever

Soft-grip handle widely covered with elastomer

Angle-adjustable one-touch hook

Replaceable carbon brushes and armature thanks to the same separate-type motor as an impact driver drill

with cord

Interchangeable with conventional NiCd or NiMH batteries

Thus the Models DV 18DL and DV 14DL are excellent in performance, operability and maintainability.

3. APPLICATIONS

  Tightening and loosening wood screw, self-tapping screw and machine screw

  Drilling into wood, plastic, mild steel and aluminum materials

  Drilling into brick and concrete block
