Product Description
YG-1 E2509 is an uncoated HSS Co8 long-length two-flute end mill with a 42° helix for aluminium. Designed with a flat shank, it provides a conventional cylindrical shank profile for aluminium milling applications. The long-length geometry supports operations requiring greater reach while retaining the E2509 series flat-shank format. Available mill diameters range from 2 to 20 mm, with 10 to 75 mm cutting lengths. Overall lengths span 54 to 141 mm, matched to the selected mill diameter. This range suits common aluminium milling work where a two-flute, high-helix cutting tool is required. The uncoated construction is the standard configuration listed for every supplied E2509 product variant.
- Uncoated HSS Co8 construction
- Two flutes with 42° helix
- Long-length E2509 geometry
- Flat shank design
- For aluminium machining
