Seco 17007047 Corner Radius End Mill 5/8 in 5 Flute Altin

Product Description

The SECO 17007047 is a solid carbide corner radius end mill designed for high-performance material removal and finishing operations on difficult-to-machine workpiece materials. Built to Series S545R specifications, this single-end, centercutting tool features a 0.6250-inch mill diameter, a 0.0200-inch corner radius, and five flutes arranged in a right-hand spiral configuration with a 45-degree high helix angle. The AlTiN PVD coating provides thermal resistance and wear protection under demanding cutting conditions. Licensed machinists, tool-and-die professionals, and CNC operators working in production or job-shop environments rely on this geometry for finishing passes requiring tight tolerances and consistent edge quality.

This end mill is suited for finishing operations on steel, stainless steel, superalloys, titanium, and hard materials. The 1.6250-inch length of cut accommodates moderate-depth profiling, slotting, and contouring applications. The straight-cylindrical shank with a 0.6250-inch shank diameter seats securely in standard toolholders. The normal pitch flute spacing and fixed helix design make this tool appropriate for stable, repeatable cuts in controlled CNC milling environments where surface finish and dimensional accuracy are the primary objectives.

Key Features

• 0.0200-inch corner radius reduces stress concentration and extends tool life on finishing passes
• AlTiN PVD coating delivers elevated hardness and oxidation resistance for high-temperature alloys and hard materials
• Five-flute configuration with 45-degree high helix promotes efficient chip evacuation and smooth surface finish
• Centercutting geometry allows plunge entry as well as peripheral milling
• Solid carbide construction maintains rigidity and dimensional stability throughout the cut
• Right-hand flute direction and right-hand cutting direction compatible with standard CNC toolholder setups

Compatibility

Designed for use with standard toolholders accepting a 0.6250-inch straight-cylindrical shank. Primary workpiece material compatibility includes steel, stainless steel, superalloys, titanium, and hard materials, corresponding to ISO material codes P, M, S, and H.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank fully within the toolholder to the recommended engagement depth before tightening; verify runout does not exceed the specified TIR maximum of 0.0005 inches prior to cutting. Power down and lock out the machine spindle before any tool change. Avoid side-loading or impact entry into the workpiece, which can chip the cutting edge on carbide tooling.
