Product Specification

OKADA TOP Series Hydraulic Breaker Chisel for Concrete and Rock Breaking

The OKADA TOP Series Hydraulic Breaker Chisel is a professional working tool designed for OKADA TOP Series hydraulic breakers. Installed at the front of the hydraulic breaker, the chisel is responsible for transferring impact energy generated by the piston into concrete, rock, asphalt, and other hard materials.

As a direct-contact wear component, the chisel plays an important role in hydraulic breaker performance. During operation, the OKADA TOP Series chisel is exposed to repeated high-impact loads, friction, bending stress, and harsh working conditions. The quality of the steel material, heat treatment process, and machining accuracy directly influence tool durability, breaking efficiency, and maintenance intervals.

Our OKADA TOP Series Hydraulic Breaker Chisels are manufactured from high-strength alloy steel with professional forging, heat treatment, and precision machining processes. The optimized metallurgical structure provides excellent impact resistance, wear resistance, and fatigue durability, ensuring reliable performance in construction, demolition, quarrying, and mining applications.

Different working profiles are available, including Moil Point, Wedge Type, Blunt Type, and Flat Type, allowing customers to select the most suitable chisel according to material conditions and operating requirements.

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