Seco 02694891 Indexable Square-shoulder End Mill 5/8 in

Product Description

The SECO 02694891 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. Built on the Nano Turbo series platform, it uses a screw-held XO.X 0602 insert style and runs at a 90-degree lead angle, delivering true square shoulders on workpieces. The tool features a 5/8 inch cutting diameter, a maximum depth of cut of 0.197 inches, and supports through-coolant delivery to manage heat and chip evacuation at the cutting zone. With a maximum spindle speed of 48000 RPM, this end mill is suited for high-speed applications where tight tolerances and clean shoulder geometry are required. It is installed by machinists and CNC tooling technicians.

This end mill is used in milling centers and CNC machining applications where square-shoulder profiling, slotting, and face milling are required. The cylindrical shank with a 5/8 inch diameter fits standard collet and toolholder setups. The R217.69-06A cutter style designation identifies its toolholder compatibility within the Nano Turbo series. The four-flute, four-insert configuration supports both roughing and semi-finishing passes. Through-coolant capability makes it appropriate for ferrous and non-ferrous materials where chip control and tool life at elevated feed rates are priorities.

Key Features

• 5/8 inch cutting diameter with 90-degree lead angle for true square-shoulder geometry
• Through-coolant delivery for effective heat and chip management at the cutting zone
• Four indexable inserts using XO.X 0602 insert style, secured by screw-hold method
• Maximum spindle speed of 48000 RPM suited for high-speed CNC milling
• Nano Turbo series platform with ISO number R217.69-00.625-0-064AN for precise toolholder matching
• Cylindrical shank for compatibility with standard collet systems

Compatibility

Designed for use with the R217.69-06A toolholder and XO.X 0602 insert style within the SECO Nano Turbo series. ISO number R217.69-00.625-0-064AN identifies the specific toolholder interface for this end mill.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before changing tooling or indexing inserts. Verify insert seating and screw torque according to the toolholder manufacturer guidelines before running. Confirm through-coolant passages are clear and coolant supply is connected before initiating high-speed cuts.
