Cutting Picks, also known as coal picks or milling teeth, are essential consumable tools designed for continuous miners, road headers, and longwall shearers. These picks are engineered to fracture hard rock, coal, and asphalt through a combination of high-impact force and rotational cutting. They are widely used in underground coal mining, tunnel excavation, and road surface milling due to their robust structural integrity.
Key Features
High-Impact Tungsten Carbide Tip: Features a premium carbide insert that offers extreme hardness and impact toughness, ensuring efficient rock penetration and a long service life.
Forged Alloy Steel Body: The pick body is CNC-machined from high-strength forged alloy steel and heat-treated to withstand the intense bending and shearing stresses of heavy-duty operation.
Self-Sharpening Rotation: Designed to rotate freely within the tool holder, which ensures uniform wear of the carbide tip and maintains a sharp cutting edge throughout its use.
Precision Retainer System: Outfitted with high-quality spring sleeves or retaining clips to ensure secure fitment in the block while allowing for easy replacement in the field.
Wear-Resistant Hardfacing: Optional hard-facing on the pick head provides an additional layer of protection against abrasive wear in highly sandy or stony strata.
