Why Choose LongTrust Machinery for RP21 Milling Teeth B229900002342
1. Dual Supply: Genuine OEM or Trusted Aftermarket
We understand that different job sites and budgets demand different solutions. Order directly from our stock:
- 100% SANY Genuine OEM teeth – full traceability, manufacturer warranty.
- LongTrust Premium Aftermarket teeth – manufactured to closely match or exceed OEM specifications, at a significantly reduced cost. All aftermarket RP21 bits use the specified 42CrMo forged body and MK8c-grade coarse-grain carbide, carefully inspected before shipment.
2. Tungsten Cost Advantage – Buy Direct from China
International tungsten raw material prices remain stubbornly high, driven by supply constraints and geopolitical factors. China is the world’s largest tungsten producer, and our local sourcing partnerships allow us to offer MK8c carbide-tipped bits at an unmatched price point. By purchasing your B229900002342 teeth from LongTrust, you lock in stable, competitive pricing with no hidden middlemen.
3. Wirtgen Compatibility Simplifies Inventory
Although the RP21 is a SANY standard part, it is not a proprietary design. Thanks to the widespread adoption of 20mm cylindrical shank systems, this milling tooth is fully interchangeable with certain Wirtgen milling drum configurations (such as W2000/W2100 using similar holder profiles). This means you can standardize your wear parts across mixed SANY-Wirtgen fleets — reducing inventory complexity and speeding up maintenance. Our team can help confirm compatibility with your specific drum model.
4. Built Tough: 42CrMo Body + MK8c Carbide
- 42CrMo forged steel shank: Offers the perfect balance of core strength and ductility. After precision hot forging and controlled heat treatment, the body withstands high bending loads without snapping, and provides a solid, long-lasting shoulder for the carbide tip.
- MK8c (coarse-grain) tungsten carbide tip: The use of coarse tungsten carbide particles bonded with cobalt under low-pressure sintering yields a tip structure that resists both abrasive wear from asphalt/concrete and impact fractures from encountering hard aggregate or manhole covers. The result is consistent penetration, fewer stops for tool changes, and lower cost per square meter milled.
5. Complete Milling Drum Setup Support
A single milling drum on an SCM2000C can hold upwards of 120 teeth, and replacing them in sets is common practice. We supply RP21 teeth in bulk packs, kits with matching Ø44mm washers and retaining clips, and can also provide the corresponding tool holders upon request. Tell us your drum width and tooth count requirement, and we’ll prepare a tailored package.

Important Selection Note – Match Your Milling Drum Model
While the RP21 tooth design is cross-compatible, final selection must match your actual milling drum model and spacing. For example, the SANY SCM2000C uses a 2,010mm wide drum and typically mounts between 120 and 144 teeth. Using an incorrect tooth count, spacing, or washer thickness can affect cutting pattern and machine balance. If you are unsure about the right configuration for your SANY or Wirtgen drum, simply send us your machine model and drum serial number, and our specialists will verify compatibility free of charge.
