1. PRODUCT NAME
Hitachi Impact Drill, Model FDV 16VB2
2. MARKETING OBJECTIVE
The new Model FDV 16VB2 is the upgraded version of the previous Model FDV 16VB, developed under the
concept for more convenient model. Thanks to the nonskid large soft grip and the push-button type forward/
reverse changeover switch, the Model FDV 16VB2 is easier to operate than the previous model.
3. APPLICATIONS
When set for "Rotation + Impact"
Drilling holes in brick, concrete and similar materials
When set for "Rotation only"
(1) Drilling holes in wood, metal, resin plate and similar materials
(2) Grinding, sanding and polishing of wood, metal and various other materials (with use of appropriate
attachments)
4. SELLING POINTS
Lightweight and compact 1.6 kg (3.5 lbs.)
Nonskid large soft grip for
comfortable operation

Masonry: 16 mm (5/8")
Steel: 13 mm (1/2")
Wood: 25 mm (1")

--- 2 ---
4-1. Selling Point Descriptions
(1) Ball and needle bearings employed for all bearings to ensure outstanding durability.
One ball bearing and one needle bearing at the spindle and two ball bearings at the armature are employed to
improve the durability appreciably.
(2) Nonskid large soft grip
Most of the conventional soft grips cover only the handle. The Model FDV 16VB2 is equipped with the nonskid
grip that largely covers both the handle and the housing (drill chuck side) to prevent slipping even if the
operator holds the Model FDV 16VB2 in various ways.
(3) Keyless chuck for quick and easy replacement of accessory tools
Adoption of a keyless chuck in place of a conventional chuck means that the bothersome chuck wrench is no
longer necessary, and that mounting and replacement of accessory tools is quicker and easier.
To mount or remove a bit from the keyless chuck, simply grasp the ring with one hand, and turn the sleeve
with the other hand.

(5) Easy to operate 2-finger sized trigger switch with variable speed control dial
The pulling amount of the trigger can be adjusted on the dial in the same manner as the Model FDV 16VB. It
is convenient for operation keeping at desired speed. The large variable speed control dial and the 2-finger
sized trigger switch are easy to operate.
(6) Easy-to-operate push-button type forward/reverse changeover switch
The Model FDV 16VB2 is 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 pushing button an obstruction at drilling.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model FDV 16VB2 Impact Drill by all of our
customers, it is very important that at the time of sales the salesperson carefully ensures that the buyer seriously
recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the
precautions listed on the Caution Plate attached to each tool.
7-1. Handling Instructions
Although every effort is made in each step of design, manufacture and inspection to provide protection against
safety hazards, the dangers inherent in the use of any electric power tool cannot be completely eliminated.
Accordingly, general precautions and suggestions for the use of electric power tools, and specific precautions
and suggestions for the use of the drills are listed in the Handling Instructions to enhance the safe, efficient use of
the tool by the customer. Salespersons must be thoroughly familiar with the contents of the Handling Instructions
to be able to offer appropriate guidance to the customer during sales promotion.
7-2. Caution Plate
The following basic safety precautions are listed on the Caution Plate attached to the main body of each tool.
(1) For Oceania and Asia
These precautions are not listed on the Name Plates of the products destined for Europe.
(2) For the U.S.A. and Canada
7-3. Precautions in Usage
(1) Direction of rotation
The bit rotates clockwise (viewed from the rear side) by
pushing the R-side of the pushing button.
The L-side of the pushing button is pushed to turn the bit
counterclockwise.

Switch trigger
Never change the direction of bit rotation while operating. Turn the power switch OFF before changing the
direction of bit rotation: otherwise, burning of the motor will result. Always use the impact drill with clockwise
rotation, when using it as an impact drill.
