*1: As of December 2017. Among 165mm cordless circular saws made by leading power tool manufacturers. (Surveyed by Hitachi Koki).
*2: In comparison with the existing model C18DBAL. The value varies according to the workpiece material and operating conditions.
*3: The runtimes are for reference purposes. They may vary according to the workpiece material and operating conditions.

  • Max Cutting Depth of 66mm

  • Lightweight and Compact for Easier Handling
Designed with the center of gravity close to the handle, the circular saw offers superior maneuverability and greatly reduces user fatigue.

  • Quick and Easy Blade Change
The flat motor housing design with soft material on the surface provides the circular saw with stability when it's laid on its side. This makes blade change easier and also prevents the workpiece from being scratched.

  • Silent Mode
  • Ideal for applications in noise-sensitive areas, such as renovation and interior work.
The Silent Mode improves motor efficiency, while lowering the noise. The operation mode automatically switches to the Power Mode when the motor load increases, enabling smooth cutting according to cutting conditions.
Noise Level Reduced by approx. 5dB (in comparison with power mode)

  • Overload Protection
Monitors changes in the motor’s rotation speed and stops the motor the instant it detects a sudden drop in speed due to the saw blade becoming bound, etc.

caution Depending on operating conditions, Overload Protection may not work or may not provide the specified performance. Make sure that the work piece is placed and supported properly, and that the main unit is held firmly during cutting. Additionally, carefully read "CORDLESS CIRCULAR SAW SAFETY WARNINGS" in the instruction manual.
