About Conical Tool Co

END MILLS, TAPERED END MILLS AND SPECIALTY CUTTING TOOLS ARE CONICAL TOOL COMPANYS LEGACY

• Conical has not only been a leading manufacturer and provider of carbide and high speed steel end mills throughout the USA, but also one of the chief innovators and trusted resources to the metalworking industry since its founding in 1944.
• Our demonstrated and recognized leadership in the industry and technical expertise has been imitated, but never matched. As the only recipient of a patent award for tapered end mills, our constant spiral helix design allows for smooth, chatter free machining. We have continued to use our engineering knowledge to produce new cutting edge, highly successful, high performance cutting tools for a variety of cutting tool applications. Our high-performance variable-helix (a.k.a. out of index, OOI, or variable spaced flutes), metric sizes, special metrics, carbide end mills, diamond coated rib tools, carbide miniatures, AlTiN coated rib cutters, tapered end mills, left hand spiral end mills, reamers and automotive tapers (tapered end mills, used by the automotive industry) are just a few of the categories that fill our continuously expanding end mill catalog.
