Efftool 1250W Power Rotary Hammer Heavy Duty Concrete Drill & Chisel Machine

The Efftool 1250W Rotary Hammer is an industrial-grade corded power tool designed for heavy-duty drilling and demolition tasks in masonry and concrete. It is frequently utilized in professional construction and renovation projects due to its high torque and impact energy. [1, 2, 3]

• Power Input: 1250W high-torque motor.
• Impact Energy: Approximately 3.5J to 5J, providing strong percussive force for breaking tough materials.
• No-Load Speed: Around 850 RPM, which is optimized for drilling through dense concrete.
• Impact Rate: Approximately 3800 to 4400 BPM (blows per minute).
• Drilling Capacity: Up to 32mm in concrete, 13mm in steel, and 40mm in wood.
• Chuck System: Uses an SDS-plus system for quick, tool-free bit changes and secure bit retention during high-impact use. 

Core Features & Functions

• Three-Mode Selector: Allows you to switch between Rotary Only (standard drilling), Hammer Only (chiseling/light demolition), and Rotary Hammer (drilling into masonry).
• Vibration Control: Often includes internal dampeners or an anti-vibration system to reduce user fatigue during prolonged operation.
• Ergonomic Design: Typically features a 360° adjustable auxiliary handle and soft-grip rear handle for improved control and comfort.
• Safety Features: Includes a safety clutch that disengages the motor if the bit jams, protecting both the user and the tool.
