Seco 03043610 Corner Radius End Mill 3/8 in 5 Flute Carbide

Product Description

The SECO 03043610 is a single-end corner radius end mill designed for precision milling in ferrous and hardened materials. Built from micrograin solid carbide with an AlTiN coating, it delivers heat resistance and edge retention in demanding cutting environments. The 5-flute, right-hand straight flute configuration produces a clean finish while maintaining rigidity at a 3/8 inch mill diameter and 0.0432 inch corner radius. With a 3 inch overall length and extended-reach geometry, this tool suits applications where clearance between the shank and workpiece is required. Licensed machinists and CNC operators install this tool in vertical and horizontal milling setups.

This end mill is suited for finish milling, profiling, and contouring operations on ferrous alloys, stainless steel, and hardened materials typically found in tooling, die work, and precision component manufacturing. The SN500R series is engineered for stub-length applications requiring extended neck reach. The 1.125 inch reach length and 0.329 inch neck diameter allow access into pockets and channels without sacrificing tool body stiffness. The cylindrical shank seats directly into standard end mill holders and collet chucks.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating provides oxidation resistance and thermal stability in high-speed cuts
• 5-flute right-hand geometry supports efficient chip evacuation and smooth surface finish
• 0.0432 inch corner radius reduces stress concentration and extends edge life at workpiece corners
• Extended reach design with 1.125 inch reach length and 0.329 inch neck diameter for deep-pocket access
• Single-end, stub-length configuration with cylindrical shank for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style replacement and standard production end mill for use in CNC machining centers and manual mills accepting a 3/8 inch cylindrical shank tool holder or collet.

Installation Notes

This tool is installed by machinists or CNC setup technicians in standard end mill holders or ER collet chucks rated for the 3/8 inch shank diameter. Confirm runout and tool holder concentricity before operation to protect the carbide cutting edges. Power down and lock out the spindle before installing or removing the tool. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and coating type.
