Item 578-9611 is a bolt-on half-arrow cutting edge, which belongs to Caterpillar's ground engaging tools (GET). Made following Cat's strict production and quality rules, it perfectly fits Cat underground loaders.

This edge works well in tough working scenes such as mining, heavy soil moving and hard material carrying. It can stand strong shock and severe abrasion. With firm structure and great wear resistance, it guards the bucket lip, avoids early damage to buckets and tooth bases, and keeps construction machines running steadily. 

Designed to resolve inherent protection weaknesses of conventional bucket edges, the Cat 578-9611 half-arrow cutting edge provides full coverage for gaps between tooth adapters. It effectively resists continuous scouring, friction and impact caused by hard materials such as ore, rock, gravel and soil. The design fundamentally eliminates common failures including edge hollowing, thinning and damage around tooth adapters, solves the problem of rapid localized bucket wear, and significantly extends the service life of both bucket bodies and tooth adapters. It reduces unplanned downtime and lowers overall parts replacement and maintenance frequency.

Core Product Features
- Efficient Bolt-On Structure: Weld-free quick assembly and disassembly saves maintenance time; stable fastening ensures no loosening under heavy-duty and high-frequency working conditions
- Extended Base Edge Service Life: Full coverage of tooth adapter gaps eliminates localized abrasion and edge hollowing, effectively extending the service life of bucket base edges
- Powerful Tooth Adapter Protection: Disperses operational impact and material friction to fully safeguard tooth adapter structures and slow down aging and wear
- Optimized Penetration Performance: Streamlined half-arrow profile reduces digging resistance and enhances penetration capability, significantly improving excavation and loading efficiency
- Genuine Premium Wear-Resistant Material: Integrally cast DH-2 wear-resistant steel with stable hardness, strong impact resistance and excellent adaptability to extreme working conditions
Application
Compatible with genuine Cat buckets and underground loaders, widely applicable to high-strength and high-wear scenarios including mining, tunnel excavation, hard material handling, earthwork construction and site leveling.
