The OSG 430-8219 is a new, USA-made 5/8" diameter, 4-flute solid carbide ball nose end mill with a TiAlN (Titanium Aluminum Nitride) PVD coating and shank flats, belonging to OSG's Series 06005 (MTD# 01-03-0033). Constructed from submicron-grade carbide, this end mill features a 5/8" cutting diameter, 3" length of cut, 6" overall length, and a 5/8" cylindrical shank with milled flats for secure pull-out-resistant clamping in Weldon-style holders. The TiAlN coating delivers high oxidation resistance and hardness up to ~3,000°F, making this tool well-suited for dry or near-dry machining of hardened steels, stainless steels, titanium alloys, and high-temperature superalloys at aggressive feed rates. The ball nose geometry enables profiling, 3D contouring, slotting, and finishing passes on complex die and mold surfaces. Manufactured in the USA and sold new in original OSG packaging.
