Description

The SECO 02694896 is an indexable square-shoulder end mill from the Nano Turbo series, designed for precision milling operations in metalworking and machining environments. Built on an R217.69-06A toolholder style with a 3/4-inch cylindrical shank, this tool accepts XO.X 0602 insert style inserts secured by screw-type holding. It features a 90-degree lead angle for true square-shoulder cuts, a maximum depth of cut of 0.197 inches, and through-coolant capability to manage heat and chip evacuation at the cutting zone. With 5 flute positions and a maximum spindle speed of 44,000 RPM, it suits high-speed, high-precision milling applications. Licensed machinists and CNC tool-and-die technicians are the primary installers.

The 02694896 is suited for square-shoulder milling in CNC machining centers where tight tolerances and surface finish quality are required. The Nano Turbo series is engineered for light radial engagement at elevated feed rates, making it applicable in aerospace, automotive, and general precision manufacturing contexts. The overall length of 3.937 inches and 3.150-inch shank length provide reach for a range of workpiece setups. Through-coolant delivery supports extended insert life in ferrous and non-ferrous materials.

Key Features

R217.69-06A toolholder style with 3/4-inch cylindrical shank for direct spindle or collet chuck mounting
5-insert cutter positions with screw-type insert retention for repeatable edge indexing
90-degree lead angle produces true square shoulders without ramp compensation
Through-coolant design channels fluid directly to the cutting zone for chip evacuation and thermal control
Maximum spindle speed of 44,000 RPM supports high-speed machining strategies
ISO designation R217.69-00.75-0-06-5AN for cross-reference and insert sourcing

Compatibility

Accepts XO.X 0602 style inserts. ISO number R217.69-00.75-0-06-5AN can be used to confirm insert and toolholder compatibility with SECO tooling catalogs. Designed for use in CNC machining centers equipped with through-spindle coolant capability and appropriate collet or chuck systems for 3/4-inch cylindrical shanks.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the spindle and coolant supply are fully de-energized and depressurized before mounting or removing the tool. Verify insert seating and screw torque per the toolholder manufacturer guidelines before running the spindle. Confirm through-coolant port alignment with the machine spindle interface before operation.
