The cutting diameter of a flush trim router bit determines how much material is removed in a single pass and how closely you can follow patterns or templates. Larger diameters (e.g., 1/2") provide more stability and smoother cuts, especially on bigger projects, while smaller diameters (e.g., 3/16") are ideal for tight curves and detailed work. The best choice depends on your project needs—having a range allows for versatility. For example, the Timberline 190-26 and Amana Tool 47104 both feature a 1/2" diameter, great for general use, while the Amana Tool MR0102 offers a miniature 3/16" diameter for precision tasks. With various options available, you can select the perfect diameter for your specific needs.
