🔍 The key is to use proper cutting parameters and technique. **Don’t cut too aggressively** – a good rule is to limit your depth per pass to about half the bit’s diameter (or less) and use a steady feed rate:contentReference[oaicite:11]{index=11}. If you push the bit too hard (too deep or fast), it can snap, especially small 1/8"" or 1/16"" bits. Also, make sure the bit is held tightly in the collet (a slipping bit can break). Avoid any side-loading prying motions and let the tool do the work. Users have reported that these bits last a long time when used with conservative feeds and speeds, but “fast and deep” cuts can cause even carbide to fail:contentReference[oaicite:12]{index=12}. In short: shallow passes, proper RPM, and a stable router setup will greatly reduce the chance of breaking a bit.
