Seco 02689812 Square Shoulder Face Mill 2 Inch Super Turbo

Product Description

The SECO 02689812 is an indexable square-shoulder face mill designed for high-performance milling on machining centers and CNC mills. Built on the Super Turbo platform using the R220.69 cutter style, this shell mill accepts 4 inserts and delivers a maximum cutting diameter of 2 inches with a maximum depth of cut of 0.4330 inches. The 0.75-inch arbor hole provides a rigid, concentric mount. Through-coolant capability keeps the cutting zone clear and extends insert life during demanding cuts. This tool is installed and operated by machinists and tooling technicians in production and job-shop environments.

The 02689812 is suited for square-shoulder milling operations on ferrous and non-ferrous workpieces in both roughing and semi-finishing applications. Supported tool applications include helical interpolation, ramping, and slotting, making this mill versatile across a range of part geometries. The right-hand cutting direction and positive axial rake combined with negative radial rake support free-cutting action with controlled chip formation. The 2-degree maximum ramping angle allows programmed ramp entries without dedicated plunge tooling.

Key Features

• 2-inch maximum cutting diameter with 0.4330-inch maximum depth of cut for square-shoulder profiling
• Through-coolant design directs coolant directly to the cutting edge for heat management and chip evacuation
• Accepts 4 XOEX1204 or XOMX 1204 inserts held by clamp and screw for secure, repeatable edge indexing
• Positive axial and negative radial rake geometry reduces cutting forces and power draw
• Supports helical interpolation, ramping up to 2 degrees, and slotting operations
• Right-hand cutting direction; compatible with standard CNC arbor setups via 0.75-inch arbor hole

Compatibility

Compatible inserts are XOEX1204 and XOMX 1204 in the XO X1204 insert size code. Cutter style designation is R220.69, part of the SECO Super Turbo series.

Installation Notes

Installation is performed by qualified tooling technicians or machinists. Confirm the machine spindle and arbor are de-energized and fully stopped before mounting or removing the cutter body. Seat the arbor to the full depth of the hub bore and torque the retention hardware per the machine tool manufacturer specification. Inspect insert pockets and seating surfaces for chips or debris before indexing or replacing inserts.
