The NPK GH Series Hydraulic Breaker Chisel is a professional working tool designed for NPK GH Series hydraulic hammers. Installed at the front of the 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. NPK GH Series hydraulic hammers are widely used in construction, demolition, quarrying, and excavation applications, with various tool configurations available for different working conditions.

As one of the most important wear parts of a hydraulic breaker, the chisel directly affects breaking efficiency, impact energy transmission, and operating cost. During continuous operation, the NPK GH Series chisel is exposed to repeated high-frequency impacts, friction, bending stress, and harsh working environments. Therefore, material strength, heat treatment quality, and machining accuracy are essential for achieving reliable performance and extended service life.

Our NPK GH Series Hydraulic Breaker Chisels are manufactured from high-strength alloy steel with professional forging, heat treatment, and precision machining processes. The optimized material structure provides excellent impact resistance, wear durability, and fatigue strength, ensuring stable performance during heavy-duty construction, demolition, quarrying, and mining operations.

Available in different profiles including Moil Point, Wedge Type, Blunt Type, and Flat Type, our replacement chisels meet different application requirements, from hard rock penetration to concrete demolition and secondary crushing.

Designed according to OEM-compatible specifications, our NPK GH Series Chisels provide a reliable aftermarket solution for hydraulic breaker repair, maintenance, and rebuilding.
