The KRUPP HM Series Hydraulic Breaker Chisel is a professional working tool designed for KRUPP HM 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 one of the most important wear components of a hydraulic breaker, the chisel directly affects breaking efficiency, working stability, and maintenance cost. During operation, the KRUPP HM Series chisel is continuously exposed to high-frequency impact forces, friction, and side pressure. Therefore, excellent material strength, proper heat treatment, and precise machining are essential for achieving long service life.

Our KRUPP HM Series Hydraulic Breaker Chisels are manufactured from high-strength alloy steel with advanced forging, heat treatment, and precision machining processes. The optimized material structure provides excellent impact resistance, wear durability, and fatigue performance, ensuring reliable operation under demanding construction, demolition, quarrying, and mining conditions.

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

Designed according to OEM-compatible specifications, our KRUPP HM Series chisels are ideal replacement parts for hydraulic breaker repair, maintenance, and rebuilding.
