4-1. Selling Point Descriptions

4-1-1. 3 modes of operation

The Model DH 30PC provides 3 functions, "Rotation and striking", "Rotation only" and "Striking only". Thus, the

Model DH 30PC is applicable to light-duty chiseling and grooving in concrete.

4-1-2. Optimum drilling mechanism for fastest speed

The drilling speed is the fastest up to 20 mm (at concrete), as the Model DH 30PC/DH 30PB has great striking energy owing to the optimum design of the rotation speed, striking frequency and the weight of the striker.

4-1-3. A highly reliable mechanism for prevention of idle hammering

The Models DH 30PC and DH 30PB are equipped with a mechanism that slides the tool retainer to prevent idle hammering. When the drill bit is pressed against the concrete surface, the striker is shifted to the striking position to start striking. When the drill bit is moved off the concrete surface, the striker is shifted forward to open the air hole so that air pressure within the air chamber no longer changes even with reciprocating movement of the piston, bringing the hammering action to a stop. Thanks to the highly reliable mechanism for prevention of idle hammering, the operability and the durability are improved.
