1. PRODUCT NAME

Hitachi Diamond Core Drill (with slip clutch function), Model DC 120VA

2. MARKETING OBJECTIVE

The diamond core drill market is showing growth due to increase of demands for reform applications and
comfortable operation (low noise and vibration). Especially, a core drill capable of drilling various types of
materials efficiently is demanded.
To meet such demand, the Model DC 120VA was developed as an advanced version of the current dry-type
Model DC 120V in efficiency and operability. The key features are as follows:
(1) 1400 W high-power motor for fast drilling (110 V product: 1250 W)
(2) Various drilling applications thanks to the speed control system with 2-speed transmission, dial-type stepless
variable speed control and constant speed control
(3) High slip torque mechanism for powerful drilling
(4) Synchronized gear shift mechanism for easy speed switching
(5) Easy-to-use rotary type side handle
(6) Vibration-isolating handle for reduced operator fatigue

3. APPLICATIONS

The Model DC 120VA can drill various workpieces using the appropriate bit or accessory tool.
