Iscar EBI-E4L 188-375/600C188CF IC902 3/16in 4-Flute Carbide Ball End Mill

This is a new Iscar EBI-E4L 188-375/600C188CF solid carbide ball nose end mill in the EBI (Extra Long Ball) series, designed for long-reach finishing and semi-finishing operations. The part number decodes as follows: D.188 = 3/16 in (0.188 in) cutting diameter, d.188 = 3/16 in (0.188 in) shank diameter, ap.375 = 0.375 in maximum axial depth of cut, L2 = extra-long reach/overall length designation (600 = 6.00 in overall length per the catalog suffix, with a necked-down fluted section), Z4 = 4 flutes, C = center-cutting, r.935 = 0.935 in cutting length (flute length), and CF = corner geometry. The grade IC902 is an AlTiN-family PVD-coated sub-micron carbide grade specifically engineered for dry and near-dry machining of hardened steels (up to ~65 HRC), stainless steels, and high-temperature alloys at elevated cutting speeds. The tool's dark AlTiN-based coating (visible in the first photo) provides high hot hardness, oxidation resistance, and reduced friction, making it well-suited for die/mold finishing, contour milling, and deep-cavity work where long overhang and tight tolerances are required; the 3/16 in diameter with a necked shank allows deep reach into cavities without holder interference.
