Finally, the type of router bit you’re using can also affect the quality of the cut. If you’re using a cheap, low-quality bit, it may not be able to make a precise cut, resulting in burning. To ensure a clean cut, it’s important to invest in a good-quality router bit that is designed for the material you’re working with.
By following these simple tips, you should be able to prevent your CNC router bit from burning the wood. Remember to regularly check your router bit for signs of wear and tear, use the correct speed settings, and invest in a good-quality router bit. With a bit of care and attention, you should be able to achieve the perfect finish every time.
