Sandvik Mining and Rock Technology is now offering the new Double TriSpec tool for use in abrasive asphalt milling conditions.
The unit is designed to reduce the risk of cause of tool failure from body wash, the premature wearing away of the steel body that surrounds and supports the brazed-carbide cutting insert. When body wash occurs, the tool’s steel body becomes vulnerable to failure, and the tool must be changed long before the carbide tip has been fully used, increasing downtime, lowering production and boosting labour costs.
Based on its popular TriSpec tools, which are designed with one carbide ring to prevent body wear, the Double TriSpec tool features an additional carbide ring. This design prevents body wash and extends the life of the steel body. The design allows for maximum use of the carbide tip, which is able to wear evenly and in proportion to the tools located across the drum. The new dual carbide ring design maintains puller groove performance throughout the life of the tool for easy removal. It also adds greater block protection, reducing costly block repair. The Double TriSpec tools are designed to fit any milling machine.
