Seco 17006979 Corner Radius End Mill 1/8 in 5 Flute Carbide

Product Description

The SECO 17006979 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding materials. It features a 1/8 inch cutting diameter, a 0.0150 inch corner radius, and 5 flutes ground in a right-hand spiral configuration with a 45-degree high helix angle. The AlTiN PVD coating provides heat resistance and extended tool life when cutting steel, stainless steel, superalloys, titanium, and hard materials. With centercutting capability and a straight cylindrical shank, this tool mounts directly into standard toolholders and is suited for precision finishing passes in CNC machining environments.

This end mill is intended for finishing applications in short-reach, close-tolerance setups on vertical and horizontal machining centers. Its 1/4 inch length of cut and 1-1/2 inch overall length make it well suited for shallow profiling, contouring, and slotting in hardened steels and exotic alloys. The normal pitch flute geometry keeps chip evacuation predictable at elevated feed rates. Machinists working with superalloys, titanium, or hardened tool steels will find this geometry appropriate for final-pass surface finishing where edge integrity and dimensional accuracy are critical.

Key Features

• Solid carbide construction with AlTiN PVD coating for heat and wear resistance in hard and exotic materials
• 0.0150 inch corner radius reduces stress concentration and improves edge life during finishing cuts
• 5-flute design with 45-degree high helix angle promotes smooth chip flow and surface finish quality
• Centercutting single-end geometry allows plunge entry and versatile toolpath programming
• Corner radius tolerance of plus or minus 0.0010 inch and mill diameter tolerance of -0.0020/0.0000 inch support tight-tolerance work
• Right-hand cut and right-hand flute direction; compatible with standard CNC toolholders

Compatibility

Designed for use with standard CNC toolholders accepting a 1/8 inch straight cylindrical shank. Rated for primary workpiece materials including steel, stainless steel, superalloys, titanium, and hard materials per material codes P, M, S, and H.

Installation Notes

Installation is performed by qualified CNC machinists or tool-and-die professionals. Ensure the toolholder collet bore and shank diameter are clean and within tolerance before clamping. Verify runout does not exceed the 0.0005 inch maximum TIR specification after seating. Follow machine tool manufacturer guidelines for speed and feed selection when cutting hardened or exotic alloy workpieces.
