    Product Description

     

    HITACHI ROTARY HAMMER DRILL DH28PBY & DH28PCY
    Features

    Approximately 2 times longer life*1 achieved by reliable structure that includes a hammering mechanism same as Hitachi large hammers.

        1. Hammering mechanism features air channel system 
        Up to 50% more volume of air cushion*1 reduces wear and damage inside cylinder.

        2. Ball bearings 
        Ball bearing seals in grease and holds temperature low to protect melt down of gear cover.

        3. New internal pressure control mechanism 
        Provides smooth airflow in or out of the gear cover to stabilize and ensure hammering action.

        *1
        In comparison with conventional models DH24PC3 / DH24PB3

    Powerful motors and optimized hammering achieved up to 30% faster drilling speed*3 to improve work efficiency.

        *2
        As of June 2013. Among 2kg class rotary hammers made by leading power tool manufacturers, surveyed by Hitachi Koki.

        *3
        A comparison of the model DH28PCY and the conventional model DH24PC3. Mean value for drilling into concrete with drill bits between 8mm and 28mm diameters. The results may vary depending on operating conditions.

    Features Hitachi's User Vibration Protection (UVP) system that reduces the vibrations from concrete drilling or chiselling with resonance occured by moving a weight in the opposite direction to the movement of the hammer. Reduction of vibration by approximately 33%*1 makes operations more comfortable.
