Cobalt
Cobalt end mills offer a strong middle ground between HSS and carbide, delivering better heat resistance and edge retention than standard HSS while remaining more shock-resistant and economical than solid carbide for certain interrupted-cut applications. Our Cobalt line includes Square End and Ball End Cobalt End Mills, Double End versions, Roughers and Rougher/Finishers (including versions optimized for aluminum), Corner Rounding End Mills, Cobalt Dovetail Cutters, and T-Slot Cutters.
Cobalt end mills are a popular choice for shops machining stainless steel, tool steel, and other tougher materials where straight carbide may be prone to chipping. As with the rest of our catalog, every Cobalt end mill is manufactured in the USA and stocked for same-day shipping.
