Seco 17000010 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The SECO 17000010 is a solid carbide corner radius end mill designed for high-performance material removal in graphite and abrasive workpiece applications. Built on the DIACR430 series platform, it features a CVD diamond coating that delivers exceptional wear resistance against the abrasive characteristics of graphite. The cutter runs a 0.030-inch corner radius on a 1/2-inch diameter tool body with 4 right-hand spiral flutes and a 30-degree medium helix angle. Center-cutting geometry allows direct plunging without a pre-drilled entry point. This tool handles both roughing and finishing operations in a single setup, reducing tool changes on the floor.

This end mill is intended for use with standard straight-cylindrical toolholders in CNC machining centers and milling machines where graphite electrodes, composite materials, or other abrasive non-metallic workpieces are being machined. The diamond coating makes it particularly well suited for electrode shops and precision mold rooms where graphite is the primary workpiece material. The short-length geometry keeps the tool rigid under aggressive feed conditions typical of graphite roughing passes.

Key Features

• CVD diamond coating for maximum abrasion resistance in graphite machining
• Solid carbide construction for rigidity and dimensional stability
• 0.030-inch corner radius reduces edge chipping and extends tool life at workpiece corners
• 4 right-hand spiral flutes with 30-degree medium helix for efficient chip evacuation
• Center-cutting design permits direct plunge entry
• Capable of both roughing and finishing material removal in a single tool

Compatibility

Designed for use with standard straight-cylindrical toolholders. Primary workpiece material is graphite; the CVD diamond coating is optimized for abrasive non-metallic materials within the DIACR430 series application range.

Installation Notes

Installation and tool changes should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the 1/2-inch straight shank fully in the toolholder and torque the retention mechanism to the toolholder specification. Verify runout does not exceed the maximum TIR of 0.0005 inches after installation to protect the diamond coating and maintain dimensional accuracy.
