Below is a list of Corn Cob Media manufacturers from Saford, North Carolina. Corn cob media is a type of dry deburring media that consists of a treated corn cob ring that has been pulverized into powder form, although the particle size can range from fine to moderate dimensions. Differing from synthetic types such as ceramic and synthetic plastic media, corn cob media is one of the two main forms of natural deburring media, the other being walnut shell media. Another type of natural deburring media, coconut shell media, is much less commonly used.
