Bi-metal blades are strong durable and versatile. Wet blasting can amplify those strengths.
Advantages include:
• Bi-metal tooth tips benefit from a smoother, more uniform surface that supports cleaner cutting and better heat management
• The controlled action of wet blasting helps preserve the bonded high-speed steel layer, reducing the risk of stress points that can be more problematic on bi-metal weld zones
• The process improves consistency across complex bi-metal geometries, where dry blasting or mechanical finishing can be too aggressive
• Coatings applied after wet blasting adhere more reliably to the differing materials in a bi-metal structure, leading to longer real-world blade life
• Peening of known areas of weakness, such as the gullet, which can enhance fatigue resistance and reduce the likelihood of crack initiation
• Honing of tooth edges through fine, consistent abrasion, improving durability and helping the blade maintain performance under demanding cutting conditions
For manufacturers striving to get the most from their bi-metal designs, wet blasting is a practical way to elevate performance without changing the core blade architecture.
