The SOOSAN SQ Series Hydraulic Breaker Chisel is a professional working tool designed for SOOSAN SQ Series hydraulic breakers. Installed at the front of the hydraulic breaker, the chisel directly contacts the working material and transfers the impact energy generated by the piston into concrete, rock, asphalt, and other hard materials.

The SOOSAN SQ Series hydraulic breaker is designed for construction, demolition, quarrying, and mining applications, featuring improved impact performance, vibration reduction, and maintenance-friendly structure. As the key wear component of the breaker, the chisel directly influences breaking efficiency, energy transfer performance, and operating cost.

During operation, the SOOSAN SQ Series chisel is exposed to repeated high-frequency impacts, friction, bending stress, and harsh working environments. A reliable chisel requires excellent material strength, optimized heat treatment, and precise machining to achieve long service life and stable performance.

Our SOOSAN SQ Series Hydraulic Breaker Chisels are manufactured from high-strength alloy steel through professional forging, heat treatment, and precision machining processes. The optimized metallurgical structure provides excellent impact resistance, wear durability, and fatigue strength, ensuring reliable operation in demanding construction and mining environments.

Available in different profiles including Moil Point, Wedge Type, Blunt Type, and Flat Type, our replacement chisels are suitable for various applications from hard rock excavation to concrete demolition.

Designed according to OEM-compatible specifications, our SOOSAN SQ Series Chisels provide a dependable aftermarket replacement solution for hydraulic breaker repair, maintenance, and rebuilding.
