🔍 Yes, SpeTool provides guidance to help you dial in the right settings. On their website, they offer a **""Speed and Feeds"" PDF guide and a CNC Tool Database** that you can download:contentReference[oaicite:17]{index=17}. These resources list suggested spindle RPM and feed rate ranges for different bit types and materials. Of course, the optimal settings can vary based on your specific router/CNC and material, but those recommendations are a great starting point. As a general tip: larger diameter bits usually run at lower RPM, and harder materials often require slower feed rates. Always start conservative and adjust as needed, and listen for a clean cutting sound.
