Supermill SAPB500MA 1/2in 4-Flute AlTiN Ball Nose Carbide End Mill

The Supermill SAPB500MA is a new, solid carbide 4-flute ball nose end mill from Supermill's All Purpose series, manufactured in Berlin, CT, USA. The MPN decodes as follows: SAP = Supermill All Purpose series, B = ball nose, 500 = 1/2 in (0.500 in) cutter diameter, M = metric/standard designation, A = AlTiN (Aluminum Titanium Nitride) coating. The tool measures 1/2 in diameter x 1-1/4 in length of cut x 3 in overall length with a 1/2 in straight shank, as confirmed on the package label. The AlTiN coating provides elevated hardness and heat resistance, making this end mill well-suited for ferrous metals, alloy steels, stainless steel, cast iron, and hardened materials in CNC milling centers and manual mills with ER or end mill holders accepting 1/2 in shank tooling. The 4-flute geometry provides a balance of chip evacuation and surface finish capability for slotting, profiling, and 3D contouring operations.
