Shank diameter is a crucial consideration because it affects both compatibility with your router and the stability during use. The most common shank sizes for purpose router bit sets are 1/4" and 1/2", with 1/2" providing greater strength, less vibration, and better cut quality, especially for heavy-duty work. For example, the Amana Tool 55468 2-Piece Edge Banding Set and Amana Tool AMS-408 8-Piece Dovetail Set both use a 1/2" shank, ideal for precision and durability. Conversely, the Timberline TRS-120 12-Piece Set features a 1/4" shank, which can be more suitable for light-duty or compact routers. There are plenty of options for both 1/4" and 1/2" shank sizes, ensuring you can match your set to your router and intended applications. These quality sets are what I use in my shop and they work great.
