Seco 17007031 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The SECO 17007031 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding machining applications. Built to S545R series specifications, it features a 1/2 inch diameter, a 0.0900 inch corner radius, and five flutes with a high-helix, right-hand spiral configuration. The AlTiN PVD coating extends tool life when cutting at elevated temperatures. With a 5/8 inch length of cut and 2-1/2 inch overall length, this single-end, centercutting tool suits CNC machining centers running finish passes on tough materials. It weighs 0.24 pounds and ships as a single unit.

This end mill is engineered for finishing cuts on steel, stainless steel, superalloys, titanium, and hard materials. Its stub-length design and high-helix geometry reduce deflection and improve surface finish on close-tolerance features. The straight-cylindrical shank fits standard toolholders, making it practical for production environments where quick changeovers are common. It is used in aerospace, die and mold, and precision part manufacturing wherever tight corner radii and superior finish quality are required.

Key Features

• 1/2 inch mill diameter with 0.0900 inch corner radius for controlled edge geometry
• 5-flute design supports higher feed rates and improved surface finish on finishing passes
• AlTiN PVD coating provides heat resistance for cutting steel, stainless steel, superalloys, titanium, and hard materials
• High-helix, right-hand spiral flutes with normal pitch improve chip evacuation
• Centercutting capability allows plunge entry without a pre-drilled hole
• Solid carbide construction maintains rigidity and dimensional stability under load
• TIR maximum of 0.0005 inches ensures consistent runout performance

Compatibility

Designed for use with standard straight-cylindrical toolholders. Primary workpiece material categories include Steel (P), Stainless Steel (M), Superalloys and Titanium (S), and Hard Material (H) per ISO material classification codes.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight-cylindrical shank fully in the toolholder and tighten to the toolholder manufacturer's specified clamping procedure. Verify runout at setup using a dial indicator before beginning the cut cycle.
