  • How long does the battery last on your battery grinder models?

    Battery life varies by usage and model: our 12V compact grinder offers extended runtime for light to medium tasks, while the 20V model is optimized for heavy-duty applications. With efficient brushless motor technology, both models maximize battery efficiency, and spare batteries are available for continuous workflow.
