Forged Heat-Treated Alloy Tool Steel 155mm Chisel Replacement for SB121 HB40G Excavator Hydraulic Breaker Hammer

155mm Heat-Treated Forged Alloy Tool Steel Chisel for Hydraulic Breaker

This 155mm diameter hydraulic breaker chisel is manufactured from high-strength forged alloy tool steel with integral heat treatment for exceptional wear resistance and impact durability. Designed for SB121, HB40G, and compatible heavy-duty breaker models.

Manufacturing Specifications

Chisel Diameter	155 mm
Material	High-Strength Forged Alloy Tool Steel
Heat Treatment	Forging + Integral Quenching & Tempering
Surface Hardness	HRC 52-58
Machining	Precision Turning & Grinding
Compatible Models	SB121, HB40G, SB151
Quality Standard	Industrial Replacement Standard

Superior Wear Resistance

The chisel undergoes a rigorous manufacturing process: alloy steel forging → rough shaping → integral quenching and tempering → precision turning → surface grinding → quality inspection. This produces a chisel with superior impact toughness at the tip and excellent dimensional accuracy for smooth operation inside the front head bushings.

Application Range

Suitable for hard rock breaking, reinforced concrete demolition, quarry operations, mining excavation, and road construction. Designed as a direct replacement for original chisels in SB121, HB40G, and SB151 series heavy-duty hydraulic breakers.
