25RC12

The 25RC12 is an aftermarket ESCO-style standard tooth — an ESCO-style conical tooth compatible with 25 series lip systems on small-to-mid excavators. Manufactured by AzuLong Wear Parts to fit ESCO lip systems. Not an original ESCO product.

Standard Profile — Application & Performance

The standard profile provides optimal balance between penetration and wear resistance. It is the most versatile tooth design for everyday excavation work, handling mixed soil conditions including topsoil, clay, and loose gravel. The profile geometry is optimized for self-sharpening wear — as the tooth wears down, it maintains a relatively sharp digging edge rather than going blunt.

Material & Durability

At 6.4 kg, this tooth is built for 10-15 ton class equipment. Manufactured from heat-treated alloy steel with HRC 48-52 hardness, this mid-range tooth is calibrated to match OEM weight and dimensional specifications. The controlled heat treatment achieves consistent hardness distribution from the tip — where abrasion resistance is critical — through to the base, where toughness prevents cracking under impact. Each tooth is inspected for dimensional accuracy before shipping.
