Seco 17000000 Corner Radius End Mill 1/16 in 4 Flute Carbide

Product Description

The SECO 17000000 is a solid carbide corner radius end mill designed for precision milling of graphite and similarly abrasive materials. It features a 1/16 inch (0.0625 inch) mill diameter with a 0.0100 inch corner radius and four right-hand flutes with a 30-degree medium helix. A CVD diamond coating protects the cutting edges against the extreme abrasiveness of graphite workpieces. The 3/16 inch (0.1875 inch) length of cut and 1-1/2 inch overall length make it well suited for detailed slot, profile, and contour work in tight geometries. Licensed machinists and CNC tool programmers specify this mill for finish and roughing operations requiring tight dimensional control.

This end mill is intended for use in CNC machining centers and manual mills where graphite electrodes, carbon-composite components, or similar non-metallic abrasive workpieces are being cut. Its centercutting geometry allows direct plunge entry, expanding its range of programmable toolpaths. The 1/8 inch straight-cylindrical shank is compatible with standard ER collet chucks and precision toolholders used in production and prototype EDM electrode work. The DIACR430 series targets material removal scenarios where standard carbide or TiAlN-coated tools would wear prematurely.

Key Features

• CVD diamond coating for extended tool life in graphite and abrasive non-metallic materials
• 0.0100 inch corner radius with a tolerance of +0.00100 to -0.00100 inch for consistent edge geometry
• Centercutting design allows direct plunge milling without a pre-drilled pilot
• Four-flute right-hand spiral configuration supports both roughing and finishing in a single tool
• 1/8 inch straight-cylindrical shank fits standard precision toolholders and ER collet systems
• Mill diameter tolerance of -0.0010/+0.0010 inch with a maximum TIR of 0.0003 inch

Compatibility

Designed for use with standard precision toolholders and collet chuck systems. Primary workpiece material is graphite; the DIACR430 series is engineered specifically for abrasive non-metallic material applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Seat the 1/8 inch shank fully into the toolholder collet and torque to the toolholder manufacturer specification. Verify runout against the 0.0003 inch maximum TIR before beginning a cut. Avoid using this diamond-coated tool on ferrous metals, as CVD diamond reacts with iron at cutting temperatures and will cause rapid tool degradation.
