The 7T3402RC Rock Teeth for Cat J400 Series Excavator are designed for demanding digging applications where high wear resistance, impact strength, and reliable penetration are essential. As a critical bucket wear component, rock teeth protect the cutting edge and help the excavator break through hard and abrasive materials during excavation, loading, quarrying, and earthmoving operations.

Manufactured from high-strength alloy steel, these rock teeth are engineered to withstand repeated impact and abrasive contact with challenging materials. Their robust construction provides a strong combination of hardness and toughness, helping reduce premature wear while maintaining structural integrity during heavy-duty operation. This makes them suitable for working with compact soil, gravel, rock, clay, and other demanding ground conditions.

The 7T3402RC Rock Teeth feature a practical profile designed to provide effective material penetration. A properly shaped tooth can concentrate digging force at the working edge, helping break hard material and improve bucket penetration. This can support more efficient excavation while reducing unnecessary resistance on the bucket and excavator.

Worn bucket teeth can significantly affect digging efficiency. As the tooth tip becomes rounded or damaged, the bucket may require greater force to penetrate the working surface, potentially increasing fuel consumption and placing additional stress on the attachment. Timely replacement helps maintain effective digging performance and protects related components such as adapters, pins, and bucket edges.

Designed for Cat J400 Series excavator applications, these rock teeth provide a practical replacement option for construction contractors, mining operators, quarry companies, equipment owners, repair workshops, and aftermarket parts distributors. Their heavy-duty design makes them suitable for excavators operating in abrasive environments where standard digging teeth may wear more quickly.

For optimal performance, operators should regularly inspect the teeth for excessive wear, cracks, deformation, or damage. The condition of the adapter and retaining components should also be checked during replacement. Proper installation and secure retention are essential for maintaining stable tooth performance during heavy excavation work.

The 7T3402RC Rock Teeth for Cat J400 Series Excavator provide a durable and cost-effective solution for maintaining bucket productivity in demanding applications. With high-strength construction, strong impact resistance, and reliable digging capability, they are designed to help excavators maintain efficient material penetration and consistent performance throughout demanding work cycles.
