Caterpillar J350 Tiger Tooth

This Caterpillar J350 tiger tooth is a replacement excavator bucket tooth for buckets using the CAT J350 tooth system. Its narrow, pointed tiger-tooth profile is designed to concentrate digging force at the tip, helping the bucket penetrate compacted ground, hard soil, rock and other difficult materials.

Tiger teeth are a popular choice where penetration is more important than a broad wear surface. The pointed profile can help improve digging performance in demanding excavation, quarrying, earthmoving and construction applications, particularly where standard general-purpose teeth struggle to break into the material.

Replacing worn bucket teeth helps maintain effective bucket penetration and can reduce unnecessary stress on the excavator, bucket cutting edge and adapters. Inspect teeth regularly for excessive wear, cracking, damaged locking arrangements or looseness, and replace components before they compromise fitment or performance.

Before ordering, confirm that your bucket uses the Caterpillar J350 tooth and adapter system. Check the existing tooth profile, adapter size and any original part reference to ensure correct fitment. The locking pin and retainer are normally separate components, so check whether these are required for your replacement.
