Seco 03043578 Corner Radius End Mill 0.0938 in 2 Flute Altin

Product Description

The SECO 03043578 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance applications. It features a 0.0938 inch mill diameter with a 0.0111 inch corner radius, two straight flutes, and a right-hand cutting direction. The tool carries an AlTiN coating, which extends tool life in abrasive and high-temperature cutting conditions. With a 0 degree helix angle and stub-length configuration, it is engineered for extended-reach work in recessed or hard-to-access part features. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers for finishing passes on hardened steels and similar materials.

This end mill is suited for milling operations in both production and job-shop environments where a small-diameter, extended-reach tool is required. Its 9/32 inch reach length and 0.0820 inch neck diameter allow access to narrow slots and recessed pockets without interference. The 1/4 inch cylindrical shank fits standard collet toolholders used on vertical and horizontal machining centers. The SN200R series is built on a micrograin carbide substrate, making it appropriate for work on hardened ferrous metals and aerospace-grade alloys where edge integrity is critical.

Key Features

• 0.0938 inch mill diameter with 0.0111 inch corner radius for controlled edge blending
• AlTiN coating for improved wear resistance and thermal stability in hard-material cutting
• Micrograin solid carbide substrate for rigidity and edge retention
• Extended-reach design with 0.2812 inch reach length and 0.0820 inch neck diameter
• 0 degree helix angle with straight flutes suited to stub-length, high-precision passes
• Single-end, right-hand cutting configuration with cylindrical 1/4 inch shank

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC machining centers accepting a 1/4 inch cylindrical shank collet or toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before tool changes. Seat the 1/4 inch shank fully into the collet and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cutting program, as small-diameter carbide end mills are sensitive to even minor misalignment.
