423-847-1140

The 423-847-1140 is an aftermarket replacement standard tooth compatible with Komatsu WA380 excavators — an aftermarket bucket tooth for Komatsu WA380-class wheel loaders in quarry and aggregate loading. Manufactured by AzuLong Wear Parts to match OEM specifications, it provides reliable digging performance for Komatsu mid-size wheel loaders in quarry and aggregate loading.

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 7.6 kg, this tooth is built for mid-size wheel loader 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.
