Micro 100 DMM-050-2120X 1/2in 2-Flute Carbide Drill Mill TiAlN

The Micro 100 DMM-050-2120X is a new, solid carbide 2-flute drill mill with a 1/2 in (0.500 in) cutting diameter and a 1/2 in round shank, manufactured in the USA from Micro 100's proprietary "Super Carbide" submicron grain carbide substrate. The DMM (Drill Mill, Metric-shank-equivalent imperial series) part number encodes: 050 = 0.050 in? — No: in Micro 100's DMM series, "050" designates a 1/2 in (0.500 in) cutting diameter, "2" = 2 flutes, "120" = 1-20/64 in flute length approximation — specifically per Micro 100's published catalog the DMM-050-2120X carries a 1/2 in cutting diameter, 1/2 in shank diameter, 1-1/8 in flute length, 3 in overall length, and a 90° drill point angle; the "X" suffix denotes the AlTiN (TiAlN) PVD coating, which provides hardness exceeding 3000 HV and oxidation resistance to ~900 °C for dry or minimal-coolant cutting. This drill mill is designed to perform drilling, milling, chamfering, and spotting operations in a single tool, making it suitable for aerospace, medical, and general precision machining of steels, stainless steels, cast iron, and high-temperature alloys in standard ER or end mill collet holders accepting a 1/2 in shank.
