1. PRODUCT NAME

Hitachi Cordless Circular Saw,  Model C 6DD

2. MARKETING OBJECTIVE

The demand for circular saws, especially cordless circular saws is growing for working on building sites with no or

few power supply facilities or sites where trailing a cord becomes an obstacle.  We have thus developed the

cordless circular saw Model C 6DD for the European markets.  Thanks to the high-strength components

equivalent to an AC-powered circular saw and the newly developed carbon brush-replaceable powerful motor, the

Model C 6DD offers AC-powered product level durability.  In addition, the Model C 6DD is equipped with a

convenient spotlight that enables operation in poor light areas for better operability.

3. APPLICATIONS

Cutting various wood materials
