SB38JM/KFW38 Cutting Teeth for Cutting Wheels of Wall Cutter

SB38JM/KFW38 Cutting Teeth for Cutting Wheels of Wall Cutter

Primary Features

• Forked Anti-Shear Mount: We engineer the base with a deep, U-shaped slotted tail. This design allows the tooth to directly straddle the base plate on the cutting wheel.
• Aggressive Milling Chisel: The cutting edge features a premium, flat-profile tungsten carbide insert. Unlike pointed tools, this broad chisel design aggressively mills, slices, and excavates through compacted clay, mixed soil, and medium-hard rock, delivering incredibly clean and straight trench walls.
• Dual-Pin Quick Replacement: Secured simply by horizontal pins or bolts through the side bores, this plug-and-play system allows for rapid tool changes on the deck. Operators can quickly unpin and replace heavily worn teeth without any welding, drastically minimizing costly rig downtime.
• Fully Customizable Configuration: We can easily adjust the slot width, pin-hole diameters, and carbide insert geometry to match your specific cutting wheels. As a direct manufacturer, we provide a perfect, highly cost-effective drop-in replacement tailored to your trenching equipment.

Manufacturing Quality

• Advanced Induction Brazing: We securely bond the heavy-duty tungsten carbide insert to the steel body using a highly controlled induction brazing process. This creates a deeply secure, impact-absorbing joint that prevents the carbide from tearing out when striking unexpected underground cobbles.
• Premium Drop Forging: We drop-forge the entire tool from a single solid block of high-grade alloy steel. This permanently aligns the internal metal grain, delivering the ultimate structural density required to survive the continuous, brutal grinding environment of diaphragm wall construction.
• Targeted Heat Treatment: We rigorously heat-treat the steel to achieve the perfect metallurgical balance. The head is hardened to combat severe abrasion from deep-trench slurry, while the forked tail remains highly ductile to absorb violent side-impacts without cracking.

Applications

We build this extreme-duty cutting tooth for deep, high-efficiency trenching:

• Diaphragm wall cutters and trench cutters (e.g., Bauer BC series cutting wheels)

• Deep foundation excavation for subways, dams, and high-rise buildings

• Milling operations in highly abrasive slurry, clay, and mixed rock formations

• Applications requiring rapid on-deck tool replacement and maximum shear resistance
