Shank size is important because it determines compatibility with your CNC machine’s collet or spindle. A secure fit ensures safety, reduces vibration, and enables accurate sanding. The most common shank sizes are 1/2 inch and 3/4 inch, which cover a wide range of CNC machines and provide strong, stable support for the sanding tool. For instance, the Amana Tool 61299 features a 1/2-inch shank, while the Amana Tool 61336 has a 3/4-inch shank, allowing users to select the best fit for their machine. Multiple shank sizes are available, so you can choose the one that matches your CNC setup.
