    The sleeve on these mandrels expands to hold a range of IDs for better versatility than solid and expanding-end mandrels. They can hold the workpiece at any position along the sleeve. To use, insert the sleeve into the workpiece before inserting the small end of the tapered body into the sleeve and pushing until it's tight. Mandrels are also known as arbors.
