The shank diameter must match your router or CNC collet size for secure, vibration-free operation. Common sizes include 1/4" and 1/2", with 1/4" shanks suited to lighter, more detailed work and 1/2" shanks preferred for heavy-duty applications or deeper cuts due to their increased rigidity. Both options are widely available—45634-K (1/4" shank) for precise signmaking and 45728-CNC (1/2" shank) for robust panel routing. Having both shank sizes in the product range allows users to choose the best fit for their equipment and the demands of their router bits for sign making project.
