YG-1 GM813030 3mm 2-Flute AlCr Coated Long Ball Nose Carbide End Mill

The YG-1 GM813030 is a new 3 mm diameter, 2-flute, long-reach ball nose solid carbide end mill from the X-POWER PRO series, manufactured in China from ultra-micrograin carbide substrate for exceptional edge retention and rigidity at small diameters. It carries a Golden-gray Y-Coating — an AlCr-based PVD coating rated to 1,100 °C — providing superior oxidation resistance, hot hardness, and reduced friction compared to standard TiAlN coatings, making it well-suited for hardened steels, stainless steels, titanium alloys, and high-temperature alloys (HRc up to ~65). Per the packaging label, the tool's dimensional specification is 3×6×8×60 mm (3 mm cutting diameter, 6 mm length of cut, 8 mm shank diameter, 60 mm overall length), with advanced honing technology applied to the cutting edges for improved chip flow and extended tool life in high-speed die/mold finishing and semi-finishing operations. The 8 mm cylindrical shank is compatible with standard ER collet chucks, shrink-fit holders, and hydraulic chucks of the appropriate bore size.
