Seco 03043600 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The SECO 03043600 is a solid carbide corner radius end mill designed for precision milling operations where edge integrity and tool life are critical. It carries a 1/4 inch diameter with a 0.0322 inch corner radius and a 0.0140 inch length of cut. The AlTiN coating improves thermal resistance and wear performance, making this tool well suited for harder workpiece materials and higher cutting speeds. With four straight flutes and right-hand cutting direction, it produces consistent finishes in short-cut applications. This tool is intended for installation and use by machinists and CNC tooling professionals in production and job-shop environments.

This end mill belongs to the SECO SN400R series and is built for short-reach, high-precision milling where corner protection and surface finish are priorities. The extended reach design, with a 1-1/4 inch reach length and 0.218 inch neck diameter, allows access into pockets and features where standard tools cannot reach. The cylindrical shank accepts standard 1/4 inch collet holders. This tool is not center-cutting and is not intended for plunge entry. It is suited for side milling, profiling, and finishing passes on hardened or abrasive materials.

Key Features

Compatibility

Designed as an OEM-style replacement-grade solid carbide end mill for use in CNC machining centers and manual mills accepting 1/4 inch cylindrical shank toolholders. Part of the SECO SN400R series.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention nut to the toolholder specification. This tool is not center-cutting — do not use for plunge or axial entry cuts.
