Seco 02772634 Indexable Square-shoulder End Mill 5/8 in

Product Description

The SECO 02772634 is an indexable square-shoulder end mill built for precision milling operations in metal-cutting environments. Part of the Turbo 10 series, this toolholder accepts XO.X 10T3.. style inserts and is compatible with XOEX and XOMX insert families. It features a 5/8 inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.354 inches. The steel body incorporates through-coolant capability and a Weldon flat shank for secure chuck retention. With a maximum spindle speed of 29,400 RPM, it suits high-throughput roughing and shoulder milling applications. Installation and setup are handled by machinists and toolroom technicians.

This end mill is designed for shoulder milling and face milling operations on machining centers and CNC mills. The 90-degree lead angle produces true square shoulders, making it suitable for stepped features, pockets, and flat-bottom profiles. The through-coolant design supports chip evacuation and tool life in ferrous and non-ferrous materials. With two cutter positions and a negative rake geometry, the toolholder is optimized for productive cuts at elevated feeds. The ISO designation for this toolholder is R217.69-00.625-3-10-2A.
