B47K17.5/DS04 Conical Teeth for Wall Cutter, Bucket, and Auger

B47K17.5/DS04 Conical Teeth for Wall Cutter, Bucket, and Auger

Primary Features

• Aggressive Point-Attack Penetration: The head is armed with a highly concentrated tungsten carbide tip. Under massive downward rig pressure, this geometry focuses all the machine’s power into a single point, aggressively fracturing and shattering solid bedrock, dense cobble, and compacted soils.
• Optimized Extraction Profile: The collar design allows for the easy insertion of specialized extraction tools. Even when severely jammed by rock dust and wet clay, operators can quickly pry the worn tooth out, drastically reducing frustrating maintenance downtime on the job site.
• Fully Customizable Configuration: We can easily adjust the carbide tip grade, shoulder thickness, and stepped shank dimensions (e.g., standard 19mm, 22mm, or 25mm). As a direct manufacturer, we provide a perfectly tailored, cost-effective drop-in replacement for your specific piling equipment.

Manufacturing Quality

• Advanced Induction Brazing: We securely bond the tungsten carbide insert into the steel body using a computer-controlled induction brazing process. This creates a deeply secure, impact-absorbing joint that prevents the carbide from shattering upon unexpected rock impacts.
• Premium Drop Forging: We drop-forge the entire steel body from a single solid block of high-grade alloy steel. This permanently aligns the internal metal grain, delivering massive structural density to survive continuous, high-torque drilling forces without snapping.
• Heat Treatment: We rigorously heat-treat the steel to achieve a dual metallurgical balance. The head is hardened to combat extreme abrasion from wet sand, while the stepped shank remains highly ductile to absorb violent drilling shockwaves.

Applications

We build this extreme-duty conical pick for deep foundation and piling operations:

• Rotary drilling augers, drilling buckets, and rock core barrels

• Diaphragm wall cutters and heavy-duty trenchers

• Piling operations in severe rock, cobblestone, and hard strata

• Deep-shaft drilling requiring maximum anti-pull-out reliability
