CM42 Conical Teeth For Auger with Pilot Bit of Foundation Drilling Attachments

CM42 Conical Teeth For Auger with Pilot Bit of Foundation Drilling Attachments

Primary Features

• Aggressive Point-Attack Penetration: We engineer the top with a highly concentrated, conical tungsten carbide tip. Instead of scraping, this specialized geometry focuses massive machine power into a single point.
• Self-Sharpening Rotation Design: The precision-machined cylindrical shank allows the pick to rotate completely freely inside the holder block during operation.
• Fully Customizable Configuration: We can easily adjust the carbide grade, tip geometry (e.g., cap, insert, or ballistic profile), and shank diameter (e.g., standard 20mm or 22mm). As a direct manufacturer, we provide a perfect, cost-effective tailored bit for your specific cutting conditions.

Manufacturing Quality

• Advanced Induction Brazing: We bond the tungsten carbide tip into the steel body using a highly controlled induction brazing process. This creates a deeply secure, impact-absorbing joint that prevents the carbide tip from shattering or popping off when striking hard rock layers.
• Premium Drop Forging: We drop-forge the entire steel body to permanently align the internal metal grain. This delivers the ultimate structural density and tensile strength required to survive continuous, high-impact blunt-force trauma without snapping at the neck.
• Through-Hardened Heat Treatment: We rigorously heat-treat the steel body. It achieves a perfect metallurgical balance—the upper head is highly hardened to resist severe asphalt and rock dust abrasion (wash-out), while the shank remains ductile enough to absorb violent shocks and prevent breaking inside the block.

Applications

We build this extreme-duty conical pick for high-impact material extraction:

• Asphalt and concrete cold planers (road milling machines)

• Underground continuous miners, shearers, and roadheaders

• Heavy-duty trenchers, soil stabilizers, and foundation drilling rigs

• Operations requiring maximum penetration and self-sharpening reliability
