Seco 17006980 Corner Radius End Mill 1/8 in 5 Flute Altin

Product Description

The SECO 17006980 is a solid carbide corner radius end mill engineered for high-performance finishing in demanding materials. It carries a 1/8 inch mill diameter, a 1/4 inch length of cut, and a 0.0200 inch corner radius, making it well suited for producing precise, radius-edged features in tight tolerances. The five-flute geometry is paired with a high-helix spiral flute design and an AlTiN PVD coating, which provides thermal resistance and wear life when cutting steel, stainless steel, superalloys, titanium, and hard materials. Overall length is 1-1/2 inches with a 1/8 inch straight-cylindrical shank. This tool is installed and run by machinists and CNC operators in production and job-shop environments.

The 17006980 belongs to the SECO S545R series and is designed for finishing operations on ferrous and high-temperature alloys. Its centercutting capability allows plunge entry, and the right-hand flute direction and right-hand cutting orientation are compatible with standard CNC machining center spindles. The short length type and normal pitch classify it as a general finishing tool where surface finish and dimensional accuracy are the priority. It accepts standard toolholders sized for a 1/8 inch shank.

Key Features

• 1/8 inch diameter solid carbide construction for rigidity in small-diameter finishing cuts
• Five-flute, high-helix spiral geometry increases material removal rate while maintaining finish quality
• AlTiN PVD coating improves heat resistance and tool life in steel, stainless steel, superalloys, titanium, and hard materials
• 0.0200 inch corner radius with a tolerance of plus or minus 0.00100 inch for consistent radius fidelity
• Centercutting design permits plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute direction for use in standard CNC spindle configurations
• No coolant-through design; external coolant or air blast is the standard delivery method for this tool class

Compatibility

Designed for use with toolholders accepting a 1/8 inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, superalloys, titanium, and hard materials as specified by SECO material codes P, M, S, and H.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Confirm the toolholder bore and runout before securing the shank; the specified maximum TIR is 0.0005 inch, so a high-precision collet or shrink-fit holder is recommended. Power down and lock out the spindle before changing tooling. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material, and verify that feeds and speeds are set for a five-flute tool at the stated length of cut to avoid tool deflection or chatter.
