FAST RESULT: The chainsaw files feature full and evenly distributed particles, enabling steady and efficient sharpening of the chainsaw chain. Achieve sharp results in just a few minutes, eliminating the need for time-consuming manual 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. EASY TO USE: Specifically designed for electric chainsaw sharpeners, these files require only two simple steps for replacement. The titanium plating enhances hardness, reducing the frequency of replacements. NOTE: Black spots on the wheel surface are normal and not indicative of coating damage. These spots result from the mixture of titanium and silicon carbide, which improves performance.
