9J4259

The 9J4259 is a Caterpillar-compatible penetration bucket tooth from the J250 series — CAT's compact tooth platform, designed for light to moderate digging with small excavators and compact equipment. Manufactured as a premium aftermarket replacement by AzuLong Wear Parts, it is designed for small excavators and compact equipment.

Penetration Profile — Application & Performance

The penetration profile features an aggressive, narrow tip geometry that concentrates digging force for maximum ground-breaking ability. This makes it the preferred choice for hard-packed soil, dense clay, and moderately rocky conditions where standard teeth may struggle to achieve adequate depth. The sharper tip also reduces bucket crowd force requirements, decreasing stress on the excavator hydraulic system.

Material & Durability

At 2.5 kg, this tooth is built for 6-10 ton class equipment. This compact tooth is manufactured from heat-treated alloy steel with a target hardness of HRC 48-52. The lighter weight makes field changes fast and reduces bucket drag, improving fuel efficiency during extended digging cycles. The alloy steel composition provides balanced resistance to both abrasive wear from sandy soils and impact damage from occasional rock contact.
