The Iscar P290 ACK2.0-3-6.3-W200-18 (Iscar catalog # 3110803) is a new, 3-flute indexable helical end mill belonging to Iscar's P290 high-feed/square-shoulder milling family, designed for full-length helical ramping, plunge milling, and deep-pocket machining. The body designation decodes as follows: ACK = helical (cork-screw) indexable end mill body; 2.0 = 2.0× diameter-to-length flute ratio (effective cutting length ≈ 2×D); 3 = 3 flutes; 6.3 = corner radius 6.3 mm (on the compatible AC… inserts); W200 = 2.000 in (50.8 mm) cylindrical Weldon-flat shank diameter; 18 = 18° helix angle. The tool accepts P290 ACKT/ACKT…IC908/IC830-family double-sided tangential inserts and uses Torx-plus screws (BLD T15/M7 + SW6-T-SH wrench); maximum insert clamping torque is 42.5 lbf·in as stamped on the shank. With its staggered, helical insert layout across three flutes, this cutter delivers smooth cutting forces and excellent chip evacuation in steel, stainless, and cast iron, and ships complete with wrench, spare screws, and IMC thread-locking lubricant.
