Iscar ECI-E5R750-1.87C75CF12 IC900 3/4in 5-Flute Carbide End Mill

This is a new Iscar ECI-E5R750-1.87C75CF12 solid carbide end mill from the ECI (Endmill Carbide Inch) product line, manufactured in Korea and graded IC900 — a PVD-coated submicron carbide grade featuring Iscar's proprietary dark TiAlN-family coating optimized for hardened steels, stainless, and high-temperature alloys. The tool is a 5-flute design with a 3/4 in (0.750 in) cutting diameter, 0.750 in corner radius profile designated R750 (indicating a full-radius / ball-nose or large corner radius geometry), 1.87 in axial depth of cut (ap), a 38° helix angle (Ha38), and a 3/4 in (Cr.12 = 12 mm ≈ 0.472 in shank — note: 'Cr.12' in Iscar's inch ECI series denotes a 3/4 in cylindrical shank), overall length L5 per Iscar's standard length series. The IC900 grade with its hard PVD coating delivers exceptional wear resistance and thermal stability, making this tool well-suited for high-speed finishing and semi-finishing of hardened steels (up to ~65 HRc), titanium alloys, and stainless steels in CNC machining centers using standard Weldon or collet-style toolholders accepting a 3/4 in shank. Iscar catalog number 261278, lot date 21/04/2020, distributor stock number 5623220.
