Merit’s Demolition Tools for Hydraulic Hammers: Precision Engineering, Metallurgical Excellence

Merit offers a comprehensive range of high-performance demolition tools, specifically designed for hydraulic hammers operating in the most demanding environments. Our tools—including moil points, chisels, blunt tools, and specialized shapes—are engineered for maximum impact energy transfer, superior wear resistance, and long service life.

Technical Specifications:

• Material: Premium-grade 42CrMo4 / AISI 4140-4142 / EN 10083-3 heat-treated alloy steel

• Manufacturing Process:

  • Forged from high-integrity steel billets for homogenous grain structure

  • Precision CNC machining for dimensional accuracy and concentricity

  • Stress-relieving and tempering to minimize residual stresses and ensure long-term fatigue resistance

• Hardness Profile:

  • Working end hardness: 50 – 55 HRC (optimized for impact resistance and wear)

  • Shank/core hardness: 32 – 38 HRC (maintains ductility to prevent fractures)

• Impact Toughness (Charpy V-Notch at -20°C): >35 Joules

• Ultimate Tensile Strength (UTS): >900 MPa

• Yield Strength: >650 MPa

• Elongation at Break: ~14%

• Fatigue Resistance: Optimized through controlled microstructure and grain refinement

Chemical Composition (Typical):

Microstructure (Post-Heat Treatment):

• Fine-tempered martensite matrix for high impact strength

• Uniform carbide distribution for wear resistance

• Grain size: ASTM 6-8 (refined for superior mechanical properties)

Applications:

• Concrete Demolition in urban construction

• Rock Breaking in quarrying and mining

• Road Trenching and utility installations

• Heavy-duty Excavation in foundations and tunneling
