Seco 03084179 Corner Radius End Mill 1/2 in 4 Flute Altin Carbide

Product Description

The SECO 03084179 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built to the STR440.2 series specification, it features a 1/2 inch mill diameter, a 1-1/2 inch length of cut, and a 0.0600 inch corner radius. The AlTiN PVD coating extends tool life when cutting hard, abrasive workpiece materials. With a variable helix geometry and 4-flute configuration, this end mill supports both roughing and finishing operations in a single tool. It is single-end, centercutting, and right-hand cutting with a high-helix spiral flute design.

This end mill is engineered for use in stainless steel, superalloys, titanium, and other hard materials — workpiece categories classified as ISO M, S, and H. The long-length, 4-inch overall length format suits deep-reach milling applications on CNC machining centers and milling machines. The straight cylindrical shank mounts directly into standard toolholders. It is appropriate for shops running tight-tolerance aerospace, medical, and industrial component work where surface finish and dimensional accuracy are both required in the same operation.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for stainless steel, superalloys, and titanium cutting
• Variable helix design reduces chatter and improves chip evacuation
• Centercutting geometry allows plunge entry and ramp milling
• 0.0600 inch corner radius reduces stress concentration and extends edge life
• Single-end, 4-flute configuration supports both roughing and finishing passes

Compatibility

Designed for use with standard CNC toolholders accepting a 1/2 inch straight cylindrical shank. Primary workpiece materials are stainless steel, superalloys, titanium, and hard materials (ISO material codes M, S, and H). Part of the SECO STR440.2 series.

Installation Notes

Installation is performed by machining professionals on CNC milling equipment. Ensure the toolholder is clean and within runout spec before seating the shank — maximum TIR for this tool is 0.0005 inches. Confirm correct tool reach and stick-out before beginning a cut, as extended reach increases deflection risk. Follow machine manufacturer torque specifications for the toolholder style in use.
