KOMAC A AT Series Hydraulic Breaker Chisel for Concrete and Rock Breaking

The KOMAC A AT Series Hydraulic Breaker Chisel is a professional working tool designed for KOMAC A and AT 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.

As a key wear component of hydraulic breakers, the chisel must withstand repeated high-energy impacts, friction, and side loading during operation. The material quality, heat treatment process, and machining accuracy directly influence breaking efficiency, tool durability, and overall hydraulic breaker performance.

Our KOMAC A AT Series Hydraulic Breaker Chisels are manufactured from high-strength alloy steel with optimized forging, heat treatment, and precision machining processes. The advanced manufacturing technology provides excellent impact resistance, wear durability, and fatigue strength, ensuring stable performance in demanding construction, demolition, quarrying, and mining applications.

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

Designed according to OEM-compatible specifications, our KOMAC A AT Series chisels provide a reliable aftermarket solution for hydraulic breaker distributors, repair workshops, contractors, and equipment owners worldwide.
