1. PRODUCT NAME
Hitachi Demolition Hammer, Model H 65SD2
2. MARKETING OBJECTIVE
The Model H 65SD2 is a grease-sealed and double-insulated demolition hammer. It has a tool retainer to permit
the use of 28.5 mm (1-1/8") air tool shank tools, standard hexagonal shank tools (combo type), and retaining
groove tools without collar. The Model H 65SD2 has been developed based on the current Model H 65SB2,
which features the use of Hitachi 30 mm hexagonal and round shank tools.
The outstanding features are as follows:
(1) Strongest demolition power and lowest noise and vibration level in this class
(2) More rigid and durable housing than that of the current model thanks to the analysis technology
(3) Soft-touch switch handle comfortably fits in the palm of a hand
(4) Unique design
3. APPLICATIONS
Demolishing of concrete and similar materials
Groove and channel digging in concrete
Groove and channel digging in asphalt and gravel roads
Tamping/compacting of asphalt and graveled roads
Cutting of asphalt
[Typical Applications]
Construction work, piping/wiring work, water supply/drain work, etc.
4. SELLING POINTS
Soft-touch grip for
easier handling
Soft touch and 360ûadjustable
side handle for easy operations
Strongest demolition power in its class
Tool retainer accepts 3 types of
28.5 mm (1-1/8") hex. shank tools
Internal double-insulation construction
with sturdy aluminum frame
Vibration-absorbing handle
for less operator fatigue

4-1. Selling Point Descriptions
4-1-1. Strongest demolition power in this class
The powerful impact force of each blow ensures efficient and easy demolishing concrete.
The demolition performance is 1.0 --- 1.4 times more powerful than that of similar products.
4-1-2. Tool retainer accepts 3 types of 28.5 mm (1-1/8") hex. shank tools
Three types of shank tools (Fig. 1) can be used in the Model H 65SD2 by
turning the tool retainer in the following two methods. Air tool shank tool
Standard hex. shank
tool (combo type)
Retaining groove tool
without collar

4-1-3. Vibration-absorbing handle for less operator fatigue
There are two vibration-absorbing rubber pads, illustrated below, designed to efficiently absorb the vibration from
the main body of the tool and minimize its transmission to the arms of the operator. One is mounted between the
handle and the gear cover; the other is mounted between the handle and the housing.
