Seco 03084177 Corner Radius End Mill 1/2 in 4 Flute Altin

Product Description

The SECO 03084177 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With a 1/2 inch mill diameter, 1-1/2 inch length of cut, and a 0.0300 inch corner radius, this tool is built for both roughing and finishing operations. The micrograin carbide substrate is coated with AlTiN via PVD process, providing thermal resistance and wear protection at elevated cutting temperatures. A variable helix design and 4-flute configuration promote chip evacuation and reduce chatter. The 40-degree helix angle supports aggressive yet stable cuts in difficult-to-machine materials.

This end mill is suited for machining stainless steel, superalloys, titanium, and other hard materials in CNC milling applications. It operates as a single-end, centercutting tool with right-hand flute direction and right-hand cutting, making it compatible with standard toolholders used in vertical and horizontal machining centers. The long-length configuration and straight cylindrical shank allow access to deeper features while maintaining rigidity. It is appropriate for production-level work in aerospace, medical, and energy-sector part manufacturing where tight tolerances and surface finish are critical.

Key Features

• AlTiN PVD coating for high-temperature wear resistance in stainless, superalloy, and titanium cuts
• Micrograin solid carbide substrate for edge strength and dimensional stability
• Variable helix design reduces harmonic vibration during cut
• Centercutting geometry enables plunge entry and full slot milling
• 0.0300 inch corner radius reduces stress concentration and extends tool life at the cutting edge
• Series STR440.2 long-length configuration for deeper feature access

Compatibility

Designed for use with standard cylindrical-bore toolholders. Primary workpiece materials are stainless steel, superalloys, titanium, and other hard materials as identified by material codes M, S, and H. Part of the SECO STR440.2 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician familiar with end mill setup procedures. Ensure the toolholder bore is clean and within tolerance before seating the shank. Verify runout with a dial indicator before cutting — TIR maximum for this tool is 0.0005 inches. Follow machine tool manufacturer guidelines for clamping torque and projection length to maintain tool stability and surface finish.
