Built for heavy-duty applications, this tooth provides exceptional penetration and maximum breakout force in challenging digging environments. The Caterpillar Bucket Teeth 4T1300 are engineered to make every excavation task efficient and hassle-free.
The OEM 4T1300 Bucket Tooth is a premium-grade, heavy-duty replacement tooth designed specifically for Caterpillar (CAT) J300 series excavators, wheel loaders, and backhoes.
Engineered for extreme ground conditions, this digging tip offers exceptional penetration and maximum wear life in challenging environments like quarrying, mining, and heavy construction.
