It is specifically engineered to handle high-impact and high-abrasion environments. Technical Specifications Shank Diameter: 30 mm (standard for the B47 series). Carbide Tip Diameter: 22 mm. Body Material: High-grade forged alloy steel. Tip Material: Large-diameter tungsten carbide insert. Designator "H": Typically signifies a "Heavy-duty" or reinforced head for increased durability in hard strata. Core Applications This tooth is used in tools such as augers, drilling buckets, and core barrels. It is best suited for: Hard Rock: Sandstone, limestone, and medium-to-hard granite. Reinforced Concrete: Ideal for drilling through existing foundations or piles. Dense Soils: Boulders, cobbles, and cemented gravels. Key Performance Features Self-Sharpening Mechanism: The round shank allows the tooth to rotate freely within the holder. This rotation ensures the carbide tip wears down symmetrically, maintaining a sharp profile throughout its lifespan. Impact Resistance: The 22 mm wide carbide base provides a larger surface area to absorb shocks, preventing the tip from fracturing when hitting hard inclusions. Efficient Penetration: The pointed geometry is designed to create stress fractures in the rock, allowing the machine to progress with less torque and downward pressure. Maintenance Tip Check the retaining clips regularly. If a clip fails and the tooth is lost, the holder (block) will wear down rapidly against the rock. Replacing a tooth is a minor expense, but repairing or replacing a welded block on an auger requires significant downtime and welding equipment.
