Using this Makita router bit set is easy. First, make sure your router is turned off and unplugged. Select the appropriate bit for your task and securely install it into the router's collet. Tighten the collet nut firmly. When starting your project, move the router slowly and steadily over the material for a smooth cut. Always wear safety goggles and ear protection to protect yourself from flying debris and noise. After use, clean the bits with a soft brush to remove any dust or debris. Store the bits in a dry place to prevent rusting. If you notice any signs of wear or damage, replace the bit to ensure optimal performance.
