Wall Cutter

Wall cutter teeth are used on diaphragm wall cutter and trench cutter systems to excavate and cut through soil, gravel, and rock during deep foundation construction.

They are mounted on the cutting wheels of the machine and act as the primary wear and cutting components. As the wheel rotates, the teeth penetrate and break the ground material, enabling continuous trench excavation for underground structures such as retaining walls, metro stations, tunnels, and foundation pits.

In short, they are replaceable cutting tools that enable efficient and controlled excavation in hard and abrasive ground conditions.

Yes—our wall cutter teeth are designed to be compatible with most standard diaphragm wall cutter and trench cutter systems used in foundation engineering.

They are manufactured according to OEM dimensional requirements to ensure proper fitment with common cutting wheel and tooth holder configurations. In most cases, they can be directly installed without modification.

However, compatibility can still depend on your specific machine model and cutting wheel design. For non-standard systems, we also provide OEM customization based on drawings, samples, or technical specifications to ensure precise matching and stable performance.

If you share your machine brand or model, we can confirm compatibility more accurately.

Wall cutter teeth are generally compatible with diaphragm wall cutter and trench cutter systems used in deep foundation construction equipment from major international brands such as Bauer, Soilmec, Casagrande, Liebherr, SANY, XCMG, and Zoomlion.

These machines all use cutting wheel systems where replaceable teeth are installed for excavating soil, gravel, and rock in foundation projects.

That said, compatibility can still vary depending on your specific machine model and the design of the cutting wheel and tooth holder.

If you are not sure, you can share your machine model, wheel type, or drawings with us. We will help confirm the correct fit and provide OEM or custom solutions if needed.

Our wall cutter teeth are made from high-strength alloy steel with tungsten carbide tips.

We use alloy steel for the body to ensure strength and impact resistance during excavation. For the cutting edge, we braze tungsten carbide inserts to improve wear resistance when working in abrasive ground conditions such as soil, gravel, and rock.

Depending on the application, the teeth are also heat-treated to improve hardness and extend service life in different working environments.

You should replace wall cutter teeth when you start to see a clear drop in cutting efficiency or visible wear on the cutting edge.

In practice, common signs include:

• The carbide tip becomes heavily worn, chipped, or rounded
• Excavation speed slows down compared to normal operation
• The cutting wheel requires more force or power to penetrate the ground
• Uneven wear appears across different teeth on the same wheel

From our experience as a manufacturer, it’s better to replace the teeth before they are completely worn out, because heavily worn teeth can increase load on the cutting wheel and reduce overall excavation efficiency.

If you are unsure, you can also send us photos of the worn teeth, and we can help you evaluate whether they need replacement.

Yes, we do.

We support both bulk supply and OEM cooperation for wall cutter teeth. For bulk orders, we can ensure stable production capacity, consistent quality, and timely delivery for ongoing construction and distributor needs.

For OEM cooperation, we can manufacture wall cutter teeth according to your drawings, samples, or technical requirements, including custom dimensions, carbide grades, and branding if needed. This is commonly used by equipment distributors, aftermarket suppliers, and construction service companies.

If you share your requirements, we can evaluate the specifications and provide a suitable production solution and quotation.
