Seco 02689809 Square-shoulder Face Mill 1.5in 5-flute

Product Description

The SECO 02689809 is an indexable square-shoulder face mill designed for high-efficiency milling operations in metalworking and machining environments. Built around the R220.69 cutter style, this tool accepts five XO X1204 inserts and delivers a maximum cutting diameter of 1.5 inches with a maximum depth of cut of 0.4330 inches. Through-coolant capability keeps the cutting zone cool during demanding cuts, extending insert life and improving surface finish. The positive axial and negative radial rake geometry helps control cutting forces while maintaining edge stability. This tool is handled by CNC machinists and toolroom professionals working on milling machines and machining centers.

The 02689809 is suited for square-shoulder face milling and ramping operations, with a maximum ramping angle of 2.50 degrees. Its right-hand cutting direction and 90-degree lead angle make it a direct fit for applications requiring true 90-degree shoulder profiles. The 3/4-inch arbor hole and 8.20 mm keyway width allow for secure mounting on standard milling arbors. Typical applications include roughing and semi-finishing of steel, cast iron, and other machinable alloys in job shop and production environments.

Key Features

• R220.69 cutter style with 90-degree lead angle for true square-shoulder profiles
• Accepts 5 XO X1204 inserts secured by clamp and screw holding method
• Through-coolant support for extended insert life and chip evacuation
• Positive axial and negative radial rake geometry for balanced cutting forces
• Maximum ramping angle of 2.50 degrees enables helical and linear ramping entries
• Right-hand cutting direction for standard spindle rotation setups

Compatibility

Designed for use with XO X1204 series indexable inserts. Mounts on standard arbors with a 3/4-inch arbor hole diameter. Intended for use in milling machines and machining centers that accommodate the Super Turbo R220.69 tooling system.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool builder guidelines and applicable shop safety procedures. Confirm spindle is fully powered down and at rest before mounting or removing the cutter body. Verify arbor and keyway engagement are secure before running; loose cutter bodies at milling speeds present a serious hazard. Follow insert manufacturer torque guidelines when seating XO X1204 inserts using the clamp and screw method.
