Let’s say you have just bought a new router or maybe, better still, you have just received a router as a gift. Now you are wondering, how many router bits do I need? What type of router bits? Should I buy a complete set and if so what types? Well, the short and simple answer is: only buy bits as you need them, especially in the beginning. As you work with your router you will come to understand more and more just how the router can aid you in your woodworking and enhance your products. As you work on different projects the needs to shape and form the wood will present itself as will need for a specific cutter profile.
You will most likely find your first five router bits will be the straight bit, round over bit, rabbeting bit, flush trim bit, and the ogee bit. For more information on each specific bit see our article “Choosing the right Router Bit, A Beginner’s Guide”. These bits can be purchased in sets or individually.
You will be able to choose the shank diameter either ¼” or ½”. If you are working with a trim router only the ¼” shank will fit but most full size routers have a steel sleeve that holds the router bit in place tightened by a collet nut which can be either size. The ½” shank is necessary for router bits that prepare cutting creating a lot of torque. The smaller shank can’t handle the force required to remove the fiber and form the expected shape.
In case of the specialized panel and cabinet router bits the blades are so large in size and remove so much material only the larger diameter shank will do. However, some woodworkers prefer the larger ½” shank for all their router bits. Although not always required, it doesn’t hurt. But if you are a beginner or weekend woodworker the smaller ¼” may serve your needs on the basic router bits if you prefer not to spend the extra expense.
In short, you have a few ways to attack the issue. Buy a basic set with the most commonly used router bits listed above or purchase the bits one at a time as needed on your projects. Buy the smaller size shank and upgrade as your needs require. Roman was not built in a day and neither will your router bit collection. Whatever you do your router will provide you with a world of new opportunities to improve and enjoy your woodworking hobby.
