Kyocera 1820-1772.266 4.50mm 4FL SE Stub Carbide End Mill

The Kyocera 1820-1772.266 is a new, solid carbide, 4-flute, square-end single-end stub length end mill with a 4.50 mm cutting diameter, manufactured in the United States. As part of Kyocera's 1820 series, this tool features a stub flute length geometry that maximizes rigidity and minimizes deflection, making it well-suited for high-precision milling of steels, stainless steels, cast iron, and non-ferrous materials in tight-tolerance applications. The dark surface visible on the shank indicates a PVD coating (consistent with Kyocera's standard finish for this series), which enhances hardness, heat resistance, and tool life at elevated cutting speeds. The 4-flute configuration promotes superior surface finish compared to 2- or 3-flute designs, and the stub length reduces overhang for improved stability in CNC machining centers using standard ER or shrink-fit collet toolholders sized for a 6 mm shank (standard for this diameter class in Kyocera's 1820 series).
