Seco 03115959 Corner Radius End Mill 1/2 in 6 Flute Carbide

Product Description

The SECO 03115959 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 1/2 inch diameter, a 1-1/8 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The 6-flute, right-hand spiral geometry with a 38-degree helix angle supports both roughing and finishing passes in a single tool. An AlTiN (PVD) coating provides thermal resistance and hardness at elevated cutting temperatures. The shank diameter is 1/2 inch with a straight-cylindrical profile, and overall length is 4 inches. This tool is intended for use in CNC machining centers with compatible toolholders.

The 03115959 is suited for cutting steel, stainless steel, cast iron, superalloys, and titanium — workpiece material codes P, M, K, and S. The short length type and 2 inch reach length make it appropriate for moderate-depth pocketing, profiling, and contouring operations where rigidity and surface finish are both priorities. The centercutting geometry allows plunge entry. This tool is used by machinists and toolroom professionals in job shop, aerospace, medical, and general manufacturing environments.

Key Features

• 0.0300 inch corner radius reduces edge chipping and improves surface finish on profiled walls
• 6-flute close-pitch design increases feed rate potential and improves chip evacuation in ferrous materials
• AlTiN PVD coating provides oxidation resistance and extends tool life in high-heat cutting conditions
• 38-degree helix angle supports smooth cutting action in both roughing and finishing passes
• Centercutting end geometry allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate delivers hardness and wear resistance in difficult-to-machine alloys

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/2 inch cylindrical shank. Part of the SECO SN638R series. For use in CNC machining centers and toolholders as specified by SECO tooling guidelines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and all energy sources isolated per applicable lockout/tagout procedures. Secure the shank in a clean, properly sized toolholder bore and torque the retention mechanism to the toolholder manufacturer's specification. Inspect the corner radius and cutting edges for chips or damage before each use. Verify runout does not exceed the 0.0005 inch TIR maximum before beginning a cut.
