Seco 03043587 Corner Radius End Mill 0.1563 in 2 Flute Altin

Product Description

The SECO 03043587 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled corner geometry and tight tolerances. It features a 0.1563-inch mill diameter with a 0.02-inch corner radius, two straight flutes, and an AlTiN coating that improves heat resistance and extends tool life in demanding cutting conditions. With a 0-degree helix angle and a single-end configuration, this tool is built for applications where rigidity and accurate corner profiling are priorities. The micrograin carbide substrate supports consistent edge integrity across the tool life. Total overall length is 2.5 inches with a 0.25-inch cylindrical shank diameter.

This end mill is suited for use in CNC machining centers and manual mills where short-length, extended-reach profiling is required. The extended reach design, with a 0.7813-inch reach length and a 0.136-inch neck diameter, allows the tool to access deeper cavities or recessed features without interference. The SN200R series is typically used in die and mold work, aerospace component machining, and precision part production where corner radius consistency is critical. Machinists and tool-and-die professionals working with ferrous and non-ferrous alloys are the primary users.

Key Features

• 0.02-inch corner radius for controlled edge geometry and reduced stress concentrations in machined corners
• AlTiN coating provides elevated heat resistance and extended tool life in high-speed and hard-material applications
• Micrograin solid carbide substrate delivers consistent edge sharpness and wear resistance
• Extended reach with 0.7813-inch reach length and reduced 0.136-inch neck diameter for cavity and recessed-feature access
• 0-degree helix angle with straight flutes for rigidity in light-chip, precision milling passes
• Single-end, short-length configuration with cylindrical 0.25-inch shank for standard collet and end mill holder compatibility

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers and milling machines accepting a 0.25-inch cylindrical shank. Part of the SECO SN200R series.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting or removing the end mill. Use an appropriate collet or end mill holder rated for the 0.25-inch shank diameter and torque the retention mechanism per the tool holder manufacturer specifications. Confirm correct tool offset and runout before engaging the workpiece.
