The Sandvik Dura-Mill WK-AL-S-31000-R125 H10F is a new, solid carbide, 4-flute square-end end mill manufactured in the USA, ground from uncoated H10F fine-grain carbide grade optimized for non-ferrous and aluminum milling. The part number decodes as follows: WK = Dura-Mill product family; AL = aluminum/non-ferrous application; S = straight (cylindrical) shank; 31000 = 1.000" (1 inch) cutter diameter; R125 = 0.125" (1/8") corner radius; H10F = uncoated fine-grain tungsten carbide grade (ISO K10 equivalent, fine grain). The label confirms dimensional encoding 1X1X1-1/4X4X125, meaning 1" cut diameter × 1" shank diameter × 1-1/4" length of cut × 4" overall length × 0.125" corner radius. Covered by US Patent 6,899,494, this tool features Sandvik's patented Dura-Mill flute geometry for high-speed machining of aluminum and other non-ferrous alloys, providing excellent chip evacuation and surface finish. Suitable for use in CNC machining centers with ER, CAT, BT, or HSK toolholders accepting a 1" straight shank.
