Description
The air hammer uses compressed air to rapidly drive a piston that hammers a tool bit, generating powerful impacts for cutting, chipping, breaking, driving, or removing materials quickly and efficiently, especially where brute force is needed. Its power, speed, and versatility make it essential in metal fabrication, demolition, and automotive shops.

Working Principle
• Compressed air drives a reciprocating piston rapidly back and forth inside the tool's cylinder.
• This piston strikes the back end of a removable tool bit (chisel, punch, cutting tool, etc.) inserted into the chuck.
• The repeated, powerful impacts are transferred directly to the working surface through the bit.

Features
• High Impact Force: Delivers powerful blows for tough cutting, chipping, and demolition tasks.
• Speed: Performs cutting, chiseling, and rivet removal much faster than manual tools.
• Simplicity & Durability: Robust design with relatively few moving parts makes them reliable and long-lasting under harsh conditions.
• Versatility: Works with a wide range of interchangeable bits (chisels, punches, scalers, rivet busters, tamping feet, etc.) for different applications.
• Lightweight: Much lighter than equivalent electric hammer tools, reducing user fatigue.

Applications
• Metalworking: Cutting, chipping, and removing welded seams or spatter; rivet busting; light shearing.
• Demolition & Chipping: Breaking up concrete, tile, masonry; removing scale/rust/corroded metal; removing floor tiles.
• Automotive: Separating ball joints, u-joints, and tie rods; removing frozen nuts/bolts; breaking exhaust components loose; rivet removal (bodywork). • Foundry Work: Removing casting deburring.
• General Maintenance: Removing stuck parts, driving heavy-duty pins or punches, compacting material (e.g., foundry sand) with tamping feet.
