Seco 75503405 Indexable Square-shoulder Face Mill 2 in

Product Description

The SECO 75503405 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Built around the R220.69 cutter style, this tool accepts five AP 1604 inserts and operates with a 0/90 lead angle, enabling true 90-degree shoulder milling. It offers a maximum cutting diameter of 2 inches and a maximum depth of cut of 0.59 inches. The right-hand cutting direction and medium pitch configuration make it well-suited for stable, high-quality surface generation. Installation and setup are handled by machining professionals and CNC operators working in production or job-shop environments.

This face mill is applied in operations requiring helical interpolation, ramping, and slotting on a variety of ferrous and non-ferrous workpiece materials. The positive axial and negative radial rake geometry supports efficient chip formation and smooth cutting action. The 3/4-inch arbor hole diameter fits standard arbor-style spindle interfaces common in vertical machining centers and milling machines. With a medium pitch and five-insert configuration, it balances cutting force distribution across the cutter body for consistent results in moderate material removal applications.

Compatibility

Designed for use with AP 1604 series indexable inserts and compatible with standard 3/4-inch arbor-style milling spindles. Conforms to ISO standards for indexable milling tool systems.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and locked out per machine tool safety procedures. Verify arbor interface fit and torque insert clamping screws using the appropriate Torx or hex key as specified by the insert manufacturer documentation. Confirm cutting direction matches spindle rotation before engaging the workpiece. Inspect all inserts for seating and condition before beginning any cut.
