ATS 2061-5000 1/2x1x3 in 4-Flute AlTiN Carbide Ball End Mill

The ATS (American Tool Service) 2061-5000 is a new, solid carbide 4-flute ball nose end mill measuring 1/2 in cutting diameter × 1 in length of cut × 3 in overall length, as confirmed directly from the label (part number 39002472, description "4FL CARB BALL SEM 1/2X1X3"). The dark blue-black coating visible on the tool is consistent with an AlTiN (aluminum titanium nitride) PVD coating, which provides hardness up to ~3,300 HV and oxidation resistance to approximately 800°C, making it well-suited for machining steels, stainless steels, hardened materials, and cast iron at elevated speeds. The semi-standard (SEM) designation in the label indicates a semi-standard length geometry — 1/2 in shank diameter matching the cutting diameter, with a 3 in OAL allowing reach into moderate-depth cavities. This end mill accepts standard ER, heat-shrink, or Weldon-flat collet chucks in 1/2 in bore, and is appropriate for profiling, contouring, and 3D surfacing operations on CNC machining centers.
