Seco 02694880 Indexable Square-shoulder End Mill 3/8 in

Product Description

The SECO 02694880 is an indexable square-shoulder end mill from the Nano Turbo series, designed for precision milling in tight-tolerance machining applications. Built around the R217.69-06A toolholder cutter style, this end mill features a 3/8 inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.197 inches. It accepts XO.X 0602 insert style inserts secured by screw-holding, and supports through-coolant delivery for extended tool life and chip evacuation. With a maximum spindle speed of 60,000 RPM and a 3/8 inch cylindrical shank, this tool suits high-speed milling operations performed by machinists and tool-and-die professionals in production and job-shop environments.

The SECO 02694880 is suited for square-shoulder milling operations where a true 90-degree wall angle is required. Its compact overall length of 2.165 inches and 2-flute, 2-insert configuration make it well-matched for small-diameter, high-RPM cutting on CNC machining centers. Through-coolant capability supports chip flushing in blind pockets and deep-feature work. This tool is appropriate for both ferrous and non-ferrous material milling where the XO.X 0602 insert style is applicable.

Key Features

• 90-degree lead angle for true square-shoulder milling walls
• Through-coolant design for improved chip evacuation and tool life
• Rated to 60,000 RPM for high-speed CNC milling applications
• Screw-held XO.X 0602 insert style for reliable insert retention
• 2-flute, 2-insert configuration optimized for small-diameter cutting
• Cylindrical shank for standard collet or hydraulic chuck mounting

Compatibility

Designed for use with XO.X 0602 insert style inserts and the R217.69-06A toolholder cutter style. ISO number R217.69-00.375-0-062AN. Compatible with CNC machining centers capable of accommodating a 3/8 inch cylindrical shank and supporting through-coolant delivery.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before tool changes. Mount the cylindrical shank in a collet, end mill holder, or hydraulic chuck rated for the target RPM. Verify insert seating and screw torque per the insert manufacturer documentation before running the spindle. Confirm through-coolant passages are clear and coolant pressure is within the machine specification before engaging the cut.
