FAST RESULT: The chainsaw files feature full and evenly distributed particles, enabling steady and efficient sharpening of the chain saw chain. Achieve professional results in just a few minutes, eliminating the need for time-consuming hand sharpening. DURABLE: Made with the latest titanium-plated diamond wheels using an advanced titanium plating process, these files offer up to 20% longer lifespan compared to non-titanium-plated alternatives.
