About Dividing Heads

Some call it a dividing head, while others call it an indexing head or a spiral head. Regardless, it does the same task: It rotates a piece of metal to cut it at a precise angle all the way around. A dividing head is usually attached to a milling machine but also works with several different power tools. The head tilts in addition to the rotation; on most machines it ranges from a 10 to 90 degree tilt. The heads come in different sizes, and the tool comes with two versions. One is a manual dividing head, which features a hand crank to move the tool. This makes it more flexible but slower; it often takes 40 cranks to make one rotation. The second is a CNC dividing head, which has a motor for operating the tool. eBay has both and the extra pieces to repair broken ones. For precise indexing without the need for complicated math, look for a dividing head that meets your product specifications.
