Seco 03043579 Corner Radius End Mill 0.0938 in 2 Flute Altin

Product Description

The SECO 03043579 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance applications. The tool measures 0.0938 inches in diameter with a 0.0111-inch corner radius and features a straight, two-flute geometry ideal for controlled chip evacuation in small-diameter cuts. An AlTiN coating provides thermal resistance and wear protection during dry or semi-dry machining. The 0.25-inch cylindrical shank seats into standard collet systems, and the single-end configuration is part of the SECO SN200R short-length series. Machinists and tooling specialists working in CNC milling operations install this tool.

This end mill is suited for finish milling, slotting, and contouring in ferrous and hardened materials where a controlled corner radius is required to reduce stress concentrations at part features. The extended-reach neck diameter of 0.0820 inches allows access to recessed features while the short flute length of 0.006 inches provides rigidity. The right-hand cutting direction and right-hand flute orientation are standard for conventional CNC vertical and horizontal machining centers. Applications include die and mold work, aerospace component finishing, and precision part manufacturing where micrograin carbide substrate and AlTiN coating performance are specified.

Key Features

• 0.0938-inch mill diameter with 0.0111-inch corner radius for controlled edge geometry
• AlTiN coating for elevated thermal resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for rigidity and edge retention at small diameters
• Straight helix, two-flute design supports chip clearance in shallow slotting cuts
• Extended-reach neck at 0.0820 inches diameter enables access to recessed workpiece features
• SN200R short series, single-end, right-hand cutting for standard CNC collet compatibility

Compatibility

Designed as an OEM-style tooling solution for CNC machining centers accepting a 0.25-inch cylindrical shank with standard ER or precision collet systems.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool runout and collet torque specifications. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing tooling. Verify collet size matches the 0.25-inch shank diameter before securing. This tool is not center-cutting and should not be used for direct plunge operations.
