The collet area portion of the end mill shank is reduced to a standard 14 diameter. However, the remaining length of our end mill, including the cutting surface, is 516. Although the diameter appears slightly larger in physical size, a 516 end mill is approximately 4-times stronger than a 14 end mill of the same material properties.
