When selecting router bits, consider the type of material you’ll be cutting, the diameter and shape of the bit, and the shank size. For example, a straight bit is used for making straight cuts, while a dovetail bit is used for creating dovetail joints. The diameter of the bit determines the width of the cut, and the shank size determines the size of the collet that will hold the bit in the router.
When choosing a router bit, it is important to consider the material you will be cutting. Different materials require different types of bits. For example, a bit designed for cutting wood will not be effective on metal. Additionally, the diameter of the bit should be appropriate for the thickness of the material you will be cutting. A bit that is too large may damage the material, while a bit that is too small may not be able to cut through the material effectively.
