The part number you are looking for likely has a slight typo in the industry nomenclature. In deep foundation and geotechnical drilling, the standard naming convention for this specific setup splits into the tooth model and its corresponding locking pin/adapter.
The parts you are referencing are t 25 series conical tooth system used on heavy-duty diaphragm wall hydraulic or mechanical grabs
The industry-standard components for this exact setup are detailed below:
The 25RC Tooth System Breakdown
The Tooth (25RC10 / 25RC12):
The "25" refers to the 25 fitment series. RC stands for Rock Chisel (or Ripper Chisel). The most common variations for diaphragm wall grabs are the 25RC10 and 25RC12. These are precision-cast alloy steel chisel teeth designed with a self-sharpening profile to penetrate dense soils, cobbles, and medium-hard rock formations during panel excavation.
The Pin / Lock (V23PN / 25RPG):
This is where the "23" in your query comes from. The standard conical or helical systems utilize a dedicated pin and rubber lock system to secure the tooth to the holder. For instance, the standard weld-on adapter for this series often takes a V23PN or 25RPG pin setup.
The Holder / Adapter (3861-25RC):
This is the heavy weld-on nose or pocket attached directly to the jaw/cutting edge of the grab bucket that the 25RC tooth slips onto.

Operational Note: Because slurry trenching involves highly abrasive environments (especially when utilizing bentonite or polymer fluids mixed with sand and gravel), monitoring the wear life of the 25RC chisel point is critical. Allowing the tooth to wear past its wear line will permanently deform the 3861-25RC weld-on holder, leading to costly pocket replacements and unexpected downtime on the rig.
