Seco 03083874 Corner Radius End Mill 0.5in 4 Flute Altin

Product Description

The SECO 03083874 is a solid carbide corner radius end mill engineered for high-demand material removal in stainless steel, superalloys, and titanium. It carries a 0.030-inch corner radius, a 0.5-inch cutting diameter, and four flutes with a variable helix design that reduces chatter and improves surface finish in difficult-to-machine materials. The AlTiN PVD coating adds thermal resistance and prolongs tool life in high-heat cutting environments. At 3 inches overall length with a 1-inch length of cut, this is a short-series tool well suited to rigid setups. It is single-end, centercutting, and right-hand cutting. Machinists, toolroom operators, and CNC programmers working in job shops and aerospace production environments will recognize this as a capable finishing and roughing tool in a single package.

This end mill fits applications where tight tolerances and controlled surface finish are required on hard or exotic workpiece materials. The extended reach geometry, with a 1.5-inch reach length and a 0.480-inch neck diameter, allows access to deeper features without sacrificing rigidity. The micrograin carbide substrate maintains cutting edge integrity in abrasive and work-hardening materials. The STRN440.2 series is intended for use with standard straight-shank toolholders, and the 0.5-inch cylindrical shank is sized for common ER and side-lock holders found on CNC machining centers.

Key Features

• Solid micrograin carbide substrate for strength in hard and exotic materials
• AlTiN PVD coating provides high-temperature resistance and extended tool life
• Variable helix flute geometry reduces harmonic vibration during cutting
• 0.030-inch corner radius reduces stress concentration at cutting corners
• Centercutting design allows plunge milling operations
• Extended reach with 0.480-inch neck diameter for access to deeper part features

Compatibility

Designed for use with straight-shank cylindrical toolholders. Primary workpiece materials are stainless steel, superalloys, titanium, and other hard materials. Part of the SECO STRN440.2 series.

Installation Notes

This tool is installed by machinists or CNC setup technicians using a compatible collet or side-lock toolholder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the toolholder does not exceed the maximum TIR specification before commencing a cut. Do not exceed recommended speeds and feeds for the workpiece material group.
