4. SELLING POINTS
4-1. Selling Point Descriptions
4-1-1. Highest drilling speed and chipping performance in the class
The drilling speed of the Model DH 30PC2 is 1.3 times higher than C and equivalent to or higher than B thanks to
the efficient transmission of the hammering energy.
4-1-2. A highly reliable mechanism for prevention of idle hammering results in prolonged service life and
comfortable operation
Conventional mechanism for prevention of idle hammering is to open and close the air holes according to the
movement of the striker. The Model DH 30PC2 has air holes located at the position unaffected by the rebound of
the striker at no load. The air holes are opened and closed by the movement of slide sleeve (A) provided around
the cylinder that interlocks with the tool and the second hammer to prevent idle hammering. This mechanism
securely prevents idle hammering even if the striker rebounds heavily when drilling holes using a large-diameter
drill bit. Thanks to the highly reliable mechanism for prevention of idle hammering, the service life of the Model
DH 30PC2 is prolonged and hammering works requiring much attention not to break the surroundings can be
efficiently performed with the Model DH 30PC2.
4-1-3. Hitachi's original and convenient 3-mode changeover mechanism
The Model DH 30PC2 is equipped with Hitachi's original and new 3-mode changeover mechanism including the
mechanism for prevention of idle hammering. Thanks to this mechanism, operation is selectable from 3 modes,
"Rotation and hammering," "Rotation only" and "Hammering only." The Model DH 30PC2 can be widely used for
not only light-duty chipping works by means of a bull point but also cornering and grooving works by means of a
cold chisel and a cutter.
