CAT Penetration Bucket Tooth J250
The 3G4259 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.
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.
At 10 kg, this tooth is built for 6-10 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.
Compatible with: CAT 307, CAT 308, CAT 311, Bobcat E50, Bobcat E55, John Deere 75G. Always verify tooth-to-adapter fitment for your specific machine configuration before ordering.
