Sunex Tools 5-Piece Standard Air Hammer Chisel Set in Tool Roll (ACS5S) is a specialized collection of pneumatic bits engineered for heavy-duty automotive and industrial applications. Designed to fit air hammers with a standard .401 shank, this set provides the necessary versatility for tasks ranging from shearing rusted fasteners to precision sheet metal cutting. By utilizing a patented chamfer design, the tools are built to protect the air hammerÕs internal components while maintaining the integrity of the chisel itself under repeated high-impact cycles.
Key Features and Benefits:
- Patented Chamfer Design: Significantly extends the operational life of the chisel and reduces impact stress on the air hammerÕs retention system.
- Enhanced Material Construction: Built with high-grade steel to resist deforming and wear, ensuring long-lasting sharpness and effectiveness.
- Black Oxide Coating: Provides rust and corrosion resistance, preventing tools from seizing when exposed to moisture.
- Standard Compatibility: The .401 shank size allows compatibility with most pneumatic hammers in the industry.
- Organized Storage: The water-repellent 600D polyester roll pouch prevents tool loss and protects the bits from environmental damage.
