YG-1 08489 2" 6-Flute HSSCo8 Long Length Center Cut End Mill

This is a new YG-1 part number 08489 (E2162902) long-length, center-cutting end mill manufactured in Korea from HSSCo8 (M42, 8% cobalt high-speed steel), providing superior heat and wear resistance over standard M2 HSS for demanding ferrous machining operations. The tool measures 2" cutting diameter × 6" flute length × 9-3/4" overall length with a 2" straight Weldon-flat shank, and features 6 flutes with a high-helix grind and a black oxide surface treatment visible on the flute body. The 6-flute geometry paired with center-cutting capability makes this end mill suited for full-slot milling, plunging, peripheral milling, and profiling in steel, stainless steel, cast iron, and tough alloys where coolant-assisted cuts at moderate speeds are employed. The Weldon-flat shank is compatible with standard shell mill arbors and side-lock toolholders accepting a 2" bore. At 9-3/4" overall length this is a long-series reach tool intended for deep-cavity milling and extended-reach applications on knee mills, horizontal mills, and CNC machining centers.
