Key Features & Benefits

🔨 Rapid, High-Impact Demolition

• 1,250 Blows Per Minute: Delivers an exceptionally high striking frequency, allowing operators to break down concrete, brick, and asphalt faster and more efficiently.
• Optimized Piston Engineering: The 35mm diameter and 120mm stroke length maximize per-blow kinetic impact, ensuring deep material penetration with every strike.

🛡️ Compact & Anti-Fatigue Design

• Lightweight 20lb Class: Weighing just 7.2 kg, this tool significantly reduces operator arm and back fatigue, extending safe working hours and overall job site productivity.
• High Maneuverability: Its compact 465mm length makes it perfect for horizontal wall breaking, indoor renovations, and working in tight, restricted spaces.

⚙️ Reliable Pneumatic Efficiency

• Consistent Airflow: The 3/4 PT air inlet and 19mm hose compatibility ensure your tool receives the steady, high-volume compressed air required for uninterrupted performance.

Usage Recommendations

• Air Supply: Always ensure your air compressor is properly rated to provide the necessary CFM (Cubic Feet per Minute) to maintain the breaker's 1,250 b.p.m strike rate without losing line pressure.
• Tool Maintenance: Add a few drops of pneumatic tool oil directly into the air inlet before each shift to lubricate the internal piston and drastically extend the life of the tool.
