Seco 02694889 Indexable Square-shoulder End Mill 5/8 in

Product Description

The SECO 02694889 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining applications. Built on the Nano Turbo platform, this toolholder accepts XO.X 0602 insert style inserts secured by a screw-holding method. It features a 5/8-inch cutting diameter, a maximum depth of cut of 0.197 inches, and a 90-degree lead angle that produces true square shoulders in a single pass. The through-coolant design directs fluid directly to the cutting zone, extending insert life and managing chip evacuation at elevated feed rates. With a maximum spindle speed of 48000 RPM, this end mill suits high-speed finishing and semi-finishing strategies.

This end mill is suited for CNC machining centers running high-speed milling cycles in ferrous and non-ferrous materials. The cylindrical shank measures 5/8 inch in diameter with a shank length of 2.756 inches, making it compatible with standard collet chucks and hydraulic toolholders of the same bore size. The Nano Turbo series is engineered for small-diameter, high-RPM applications where rigidity and runout control are critical. Typical users include CNC machinists, tool-and-die shops, and precision manufacturing facilities requiring reliable square-shoulder milling in tight-tolerance workpieces.

Key Features

• 90-degree lead angle produces true square shoulders and vertical walls in a single pass
• Through-coolant capability directs fluid to the cutting zone for improved chip evacuation and insert life
• Accepts XO.X 0602 insert style, retained by screw-holding method for secure clamping
• Maximum spindle speed of 48000 RPM supports high-speed milling strategies
• Three-flute, three-insert configuration balances material removal rate with surface finish quality
• Cylindrical shank for compatibility with standard collet and hydraulic toolholding systems

Compatibility

Designed for use with XO.X 0602 insert style inserts. ISO number R217.69-00.625-0-063AN. Cutter style designation R217.69-06A. Verify insert grade and geometry selection against workpiece material and cutting conditions before use.

Installation Notes

Installation is performed by CNC machinists or toolroom personnel. Power down and lock out the spindle before seating or removing inserts or loading the toolholder into the machine. Torque the insert-retention screw to the value specified in the SECO tooling documentation for the XO.X 0602 insert style. Confirm runout at the cutting edge with a dial indicator after clamping to ensure performance at high RPM.
