Seco 10008600 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The SECO 10008600 is a single-end corner radius end mill engineered for high-performance milling in demanding machining environments. Built from solid carbide and coated with an HTA finish, it delivers wear resistance and thermal stability in both dry and semi-dry cutting conditions. The tool features a 1/2-inch diameter, a 1-1/4-inch length of cut, and a 0.0300-inch corner radius that blends the floor and wall of a pocket while reducing stress concentrations in the workpiece. With 5 flutes and a 40-degree helix, this end mill is suited for machinists and tool-and-die professionals running production or precision jobs on CNC machining centers.

This end mill is designed for slot milling, peripheral milling, and pocket milling operations where a controlled corner radius is required to reduce part stress or meet drawing callouts. The variable index and variable helix geometry help dampen chatter during aggressive cuts, making it a practical choice for harder materials and long-reach setups. It fits a 1/2-inch straight-cylindrical shank holder and is part of the SECO STS540 series, which targets high-efficiency roughing and finishing in ferrous and non-ferrous alloys.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• HTA coating provides elevated thermal protection and extended tool life
• 0.0300-inch corner radius reduces stress risers and protects part geometry
• Variable index and variable helix design dampens vibration and chatter
• 5-flute configuration supports higher feed rates and improved finish quality
• Right-hand cutting, right-hand flute direction for standard CNC spindle use

Compatibility

Part of the SECO STS540 series. Fits standard 1/2-inch straight-cylindrical shank toolholders including collet chucks, end mill holders, and hydraulic chucks compatible with a 1/2-inch shank diameter.

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 shank to the full recommended engagement depth in the toolholder and torque the retention hardware per the toolholder manufacturer's specifications. Verify runout with a dial indicator after installation before commencing a cut.
