Seco 17005001 Ball End Mill 1/4 in 4 Flute Carbide Cvd

Product Description

The SECO 17005001 is a solid carbide ball end mill engineered for demanding material removal in both roughing and finishing operations. Featuring a 0.250-inch mill diameter and a 0.750-inch length of cut, this four-flute tool delivers high chip evacuation efficiency in a compact form factor. The CVD diamond coating provides exceptional surface hardness and wear resistance, making it well suited for cutting abrasive non-ferrous materials, composites, and graphite. The 30-degree medium helix angle balances cutting forces and surface finish quality. Licensed machinists and tooling engineers working in precision manufacturing environments are the primary users of this tool.

This end mill is intended for CNC machining centers and manual mills where a small-diameter ball profile is required for contour milling, 3D profiling, and slot finishing. The single-end, straight-cylindrical shank design with a 0.250-inch shank diameter provides direct mounting in standard collet or end mill holder systems. The tool carries a 2.500-inch overall length, keeping deflection low during close-tolerance work. It is part of the SECO DIAB430 series, which is built around CVD diamond coatings for high-performance cutting of abrasive workpiece materials.

Key Features

• Solid carbide construction for rigidity and tool life in abrasive applications
• CVD diamond coating for superior wear resistance on non-ferrous and composite materials
• Four-flute, right-hand spiral design supports both roughing and finishing in a single tool
• 30-degree medium helix angle balances cutting forces and chip flow
• 0.1250-inch nose radius delivers accurate ball-profile contours
• Mill diameter tolerance of +0.0000 / -0.0020 inches for consistent dimensional accuracy
• TIR maximum of 0.0005 inches ensures minimal runout at the cutting edge

Compatibility

Part of the SECO DIAB430 series (catalog number DIAB430-0.250-D3-B.0-Z4). Designed for use in standard 1/4-inch collet or end mill holder systems on CNC and manual milling machines requiring a ball-profile end mill for contour and finishing operations.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Use a calibrated torque wrench and the appropriate collet or end mill holder to secure the straight-cylindrical shank to the specified clamping torque per the machine tool manufacturer. Inspect the CVD diamond coating for chips or delamination before each setup, as coating damage will accelerate wear and affect workpiece finish. Follow shop-floor tooling procedures and applicable ANSI or machine tool safety standards when setting tool offsets and running prove-out passes.
