TOKU TNB Series Hydraulic Breaker Chisel for Concrete and Rock Breaking

The TOKU TNB Series Hydraulic Breaker Chisel is a professional working tool designed for TOKU TNB Series hydraulic breakers. Installed at the front of the hydraulic breaker, the chisel directly contacts the working material and transfers impact energy generated by the piston into concrete, rock, asphalt, and other hard materials. TOKU TNB hydraulic breakers are widely used in construction, demolition, civil engineering, quarrying, and mining applications, covering various excavator classes.

As one of the most important wear components of a hydraulic breaker, the chisel plays a key role in impact energy transmission, breaking efficiency, and equipment operating cost. During continuous operation, the TOKU TNB Series chisel is exposed to repeated impact loads, friction, bending stress, and demanding working conditions. Therefore, material strength, heat treatment quality, and machining accuracy directly influence tool durability and working performance.

Our TOKU TNB 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 reliable performance during construction, demolition, rock breaking, and mining operations.

Available in different working profiles including Moil Point, Wedge Type, Blunt Type, and Flat Type, our replacement chisels are suitable for various applications, from hard rock penetration to concrete demolition and secondary breaking. TOKU TNB Series chisels are commonly supplied for hydraulic breaker models including TNB-3E, TNB-4M, TNB-5M, TNB-08M, TNB-22E, and other TNB models.

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