*2: The value varies according to the state of battery charge and other operating conditions.

  • Faster Cutting Speed
Handles heavy duty applications with an efficiency impossible with conventional 18V grinders.

Cutting Speed Comparison
When cutting a groove 5mm deep and 600mm long in mortar with a 105mm diamond wheel.

*The value is for reference purposes. It may vary according to the workpiece material or other operating conditions.

  • Increased Overload Capacity
The motor is so powerful as to keep the rotation speed constant, and it is less likely to become overloaded.

Comparison of Overload Capacity
When grinding steel with a 125mm grinding wheel.

*The value is for reference purposes. It may vary according to the workpiece material or other operating conditions.

  • Excellent Handling
Smallest Grip Circumference in its Class*
Lightweight and compact body with a slim grip and small head offers easy handling and efficient operation.
