Seco 03084130 Corner Radius End Mill 1/8 in 4 Flute Carbide

Product Description

The SECO 03084130 is a solid carbide corner radius end mill built for demanding material removal in stainless steel, superalloys, and titanium. It carries a 1/8 inch cutting diameter, a 0.0100 inch corner radius, and an AlTiN PVD coating applied by physical vapor deposition for high-temperature wear resistance. The four-flute, single-end geometry supports both roughing and finishing passes in a single tool. With a stub-length design and 1/8 inch length of cut, this end mill is suited for precision work in tight pockets and contoured surfaces. Licensed machinists and CNC tooling specialists are the primary users of this tool in production and job-shop environments.

This end mill is designed for use in hard-material applications where tool life and dimensional consistency are critical. Its variable helix construction helps reduce harmonic chatter during aggressive cuts in stainless steel, superalloys, and hard materials classified under ISO material groups M, S, and H. The straight-cylindrical shank seats directly into standard toolholders with a 1/8 inch bore. The Series STR440.2 designation places this tool within a family optimized for high-performance milling of difficult-to-machine alloys.

Key Features

• 0.0100 inch corner radius reduces stress concentration at the cutting edge and extends tool life in hard materials
• AlTiN PVD coating provides oxidation resistance and hardness at elevated cutting temperatures
• Variable helix geometry minimizes chatter and vibration during cuts
• Solid micrograin carbide construction delivers rigidity and edge retention in stainless steel and superalloys
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut and right-hand flute spiral for standard CNC milling setups

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/8 inch shank diameter. Intended for milling stainless steel, superalloys, titanium, and hard materials per ISO material groups M, S, and H.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before loading or changing the tool. Seat the 1/8 inch straight-cylindrical shank fully into the toolholder bore and verify runout against the TIR maximum of 0.0005 inch before commencing a cut. Follow the toolholder manufacturer's clamping specifications and consult the machine tool's programming documentation for appropriate feeds and speeds for the target workpiece material.
