Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The V43SYL bucket tooth is one of the most widely used tooth profiles for the Hitachi EX350 series due to its balanced shape, reinforced side walls, and excellent penetration angle. Designed to handle continuous high-load excavation, it provides exceptional strength and resistance against impact, bending, and abrasive wear. Whether used for trenching, loading, earthmoving, or rock excavation, this tooth helps operators maintain productivity and fuel efficiency across various soil types.
Compared to standard chisel teeth, the V43SYL design offers a moderate taper and smooth curvature, allowing faster bucket entry with less engine load. It is particularly effective in compacted soil, mixed rock, sandstone, and heavy clay environments.
Advanced Alloy Steel for Maximum Durability
To meet the requirements of mid-to-large excavators like the EX350, the tooth body is cast using premium alloy steel such as 30CrMnSi or low-alloy boron steel, both providing high tensile strength and controlled hardness after heat treatment.
The combination of:
- High-carbon composition (for hardness)
- Chromium and manganese additives (for toughness)
- Uniform controlled cooling (to avoid internal stress)
ensures the V43SYL tooth can withstand long-term impact without fracture and maintain its shape as it wears.
Throughout manufacturing, each tooth is subjected to metallographic analysis and hardness testing to guarantee consistent mechanical performance.
See installation diagram above showing how the bucket tooth is mounted onto the adapter and secured with a locking pin.
Each tooth is designed for specific digging tasks—general-purpose (flat), penetration (sharp), or rock-type (ribbed/reinforced)—and works in tandem with the adapter to transfer digging force.
Optimized Heat Treatment for Long Wear Life
Each V43SYL tooth goes through a specialized heat treatment cycle tailored to mid-size excavator operations:
- Austenitizing to strengthen overall material structure
- Quenching to achieve high surface hardness
- Tempering to retain core toughness and prevent brittleness
The final hardness typically reaches HRC 48–52, allowing the tooth to resist groove wear, edge rounding, and point deformation for extended periods. This significantly reduces the cost-per-hour of the machine and minimizes downtime due to frequent tooth changes.
V43SYL Tooth Profile Advantages
Unlike many general-purpose tooth shapes, the SYL series (Sharp and Long) provides a well-balanced geometry that improves cutting efficiency while maintaining structural stability. Key benefits include:
- Improved Penetration Efficiency
The tapered point allows clean entry into compact materials, reducing bucket resistance and enhancing cycle speed. - Reinforced Shoulder Design
The thickened shoulders help distribute force evenly during side loads, reducing the risk of cracking or bending in heavy-duty digging. - Stable Wear Pattern
The tooth wears gradually while maintaining a sharp profile, ensuring consistent performance until the end of its service life.
Secure Fit with V43 Series Adapters
Machined mounting surfaces ensure steady contact and tight locking, preventing vibration and tooth loss even under repeated impact.
Compatibility and Usage
The V43SYL tooth fits:
- Hitachi EX350 / EX350H / EX350-3 / EX350-5
- Other excavators using V43 adapters and pins
Typical working applications include:
- Heavy digging in mixed gravel and compact soil
- Quarry excavation and loading
- Foundation trenching
- Road construction and land clearing
- Pipeline preparation and general earthmoving
