The Data Flute MH50500C11 WF (catalog number D50530) is a solid carbide, 5-flute, variable-helix end mill in the MH (Multi-Helix) series, ground to a 1/2 in cutting diameter with a 1/2 in shank diameter, 1-1/4 in length of cut, and 3 in overall length. The Weldon flat (WF) on the shank provides positive anti-pullout engagement with set-screw style toolholders, making it reliable for aggressive material removal in steel, stainless steel, titanium, and other ferrous alloys. The tool carries a dark Physical Vapor Deposition (PVD) black coating — visible across all product photos — which reduces friction, improves wear resistance, and extends tool life in demanding milling operations. The "C11" suffix in the part number designates a center-cutting geometry with 11° helix variation (variable helix), which suppresses chatter and enables high-efficiency milling (HEM) and trochoidal toolpath strategies. Manufactured in Pittsfield, MA, USA by Data Flute and supplied new in the original sealed tube with factory label intact.
