20V Brushless Cordless Rotary Hammer (Model : 8678)

Features

• Maintenance-Free Brushless 20V DC Motor

  Eliminates carbon brush wear for cooler, highly efficient operation. Offers up to 1,400 RPM no-load speed and 4,800 BPM impact rate, making concrete drilling effortless and fast.

• 2.5 Joules Impact Energy & 4-in-1 Mode Selector

  Features 4 versatile operating modes: Drilling, Hammer Drilling, Chiseling, and Chisel Alignment (allowing bit adjustment to optimum working angles for chipping).

• Torque Limiting Safety Clutch

  Automatically disengages gear drive if the drill bit binds in rebar or hard concrete, preventing dangerous high-torque kickback reactions and protecting the motor.

• Double-Insulated PA6-GF30 Body Construction

  Built with high-strength glass-fiber reinforced nylon (PA6-GF30) body and double insulation design (insulated rotor and stator paper), providing maximum heat resistance and operator electrical safety.

• Optimized Shaft Ventilation & Anti-Vibration Design

  Features advanced airflow design to dissipate motor and gear heat effectively, combined with a 360-degree anti-vibration auxiliary handle to minimize user fatigue during prolonged use.

• Smart Cell Protection 4.0Ah Battery System

  Includes two 20V 4.0Ah battery packs with built-in electronic protection against overload, over-discharge, and overheating.
