Shank diameter (SHK) affects the stability and compatibility of the bit with your CNC machine. A thicker shank provides more rigidity and less vibration, which is especially important for larger diameter bits or heavy-duty applications. Common shank sizes available are 1/4", 1/2", and 3/4", as seen in the RC-1126 (1/2" SHK), DRB-416 (1/4" SHK), and RC-2370 (3/4" SHK). Choosing the right shank diameter ensures a secure fit in your machine and optimal performance for your application. Multiple options are available to fit various collet sizes and machine requirements.
