Ingersoll Cutting Tool Company has long been one of the world's leading suppliers of metal removal tooling. Since our first cutting tool patent in 1889, we have strived to provide the most innovative and productive metal removal solutions on the market. We pioneered the development of indexable carbide end mills. We were the first to introduce the On-Edge_ insert configuration. We received the first patent for an indexable ball nose end mill and quickly followed with the first two-effective ball nose. Today, Ingersoll Cutting Tools offers the widest range of milling products in the world.
