7T3402

The 7T3402 is a Caterpillar-compatible standard bucket tooth from the J400 series — CAT's bridge between mid-size and heavy-duty, built for contractors who need more digging force than J350 but don't require the full J450 system. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for mid-large excavators for demanding commercial projects.

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 9.5 kg, this tooth is built for 25-35 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.
