The cutting diameter (D) affects both the size of the profile you can achieve and the stability of the bit during operation. A larger diameter allows for a broader, smoother curve and often means the round over router bit can handle more aggressive cuts, while a smaller diameter is ideal for tight spaces and intricate work. Choosing the right diameter helps ensure clean results and minimizes tear-out. Options like the Amana Tool MRR108 (5/16" D), Amana Tool 49504 (1" D), and Amana Tool 49520 (2" D) demonstrate the diversity in cutting diameter, making it easy to find a bit suited to your material and desired profile. Multiple diameters are available for optimal matching to your project.
