Trim router bits are used to make the edge of one material flush with that of another. They’re guided with the help of a built-in pilot bearing that can be situated at the top or bottom. Our list features both of these types of configurations. There’s also the CMT Flush, which cleverly incorporates a bearing on each end, which can make your job easier by not having to reposition your stock or your router, accordingly.
Another factor to consider is flute count. In general, bits with more flutes have stronger cores. The durable Bosch model on our list incorporates three of them, and it works like a pro on a range of materials. If you’re working with softer wood, we included plenty of reliable, two-fluted choices, including the heat-forged Freud 42-114 and the rugged Amana Tool 47126.
For woodworking safety, always wear eye and ear protection, as well as a dust mask. Keep your hands, body, clothes, and hair away from the blades, and be sure to disconnect the power when you're making adjustments to your machine, and keep it unplugged when it's not in use.
