Seco 17005013 Ball End Mill 1/8 in 4 Flute Cvd Diamond

Product Description

The SECO 17005013 is a solid carbide ball end mill designed for high-precision milling in demanding applications. Part of the DIALB430 series, it features a 1/8 inch (0.1250 inch) mill diameter, a 1 inch length of cut, and a 3 inch overall length, making it an extra-long tool suited for deep-cavity work. The CVD diamond coating delivers exceptional hardness and wear resistance, extending tool life in abrasive materials such as graphite, ceramics, composites, and hardened nonferrous alloys. With four flutes, a 30-degree helix angle, and right-hand cutting and flute direction, this end mill handles both roughing and finishing passes in a single setup. It is installed by machinists and tooling professionals working with CNC machining centers.

This ball end mill is well-suited for precision contouring, 3D profiling, and slotting in applications that require reach into deep pockets or complex geometries. The extra-long length of cut and straight-cylindrical shank allow secure toolholder engagement while maintaining access to features that shorter tools cannot reach. The centercutting geometry supports plunge entry as well as conventional lateral passes. Typical use cases include aerospace component machining, mold and die work, and precision part fabrication where abrasive workpiece materials accelerate wear on uncoated or PVD-coated tooling.

Key Features

• CVD diamond coating for superior wear resistance in abrasive and nonferrous materials
• 4-flute spiral geometry supports both roughing and finishing in a single tool
• Extra-long 1 inch length of cut and 3 inch overall length for deep-cavity access
• 30-degree medium helix angle balances chip evacuation and cutting stability
• Centercutting design allows direct plunge entry
• Straight-cylindrical shank for standard collet or end mill holder compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in CNC machining centers and manual mills accepting a 1/8 inch straight-cylindrical shank. Part of the SECO DIALB430 series; catalog reference DIALB430-0.125-D8-B.0-Z4.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked before inserting or removing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout does not exceed the rated TIR maximum of 0.0005 inches before beginning a cut; excessive runout accelerates edge wear and reduces surface finish quality.
