Seco 17000106 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The SECO 17000106 is a solid carbide ball end mill designed for precision milling in demanding cutting environments. Part of the DIALB430 series, it features a CVD diamond coating that extends tool life when machining highly abrasive materials such as graphite, carbon fiber, ceramics, and nonferrous composites. With a 0.5-inch mill diameter, a 1.375-inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle, this end mill is engineered for both roughing and finishing passes. The single-end, straight-cylindrical shank design fits standard milling chucks and collets. Machinists and tool-and-die professionals use this tool in CNC machining centers where tight tolerances and surface finish consistency are required.

This end mill is suited for high-precision milling applications in both production and prototype environments. The CVD diamond coating makes it particularly effective when machining nonferrous, composite, or abrasive workpiece materials that would rapidly wear uncoated or PVD-coated carbide tools. The 4-inch overall length provides adequate reach for standard depth applications without compromising rigidity. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. The DIALB430 series is positioned for shops requiring tight dimensional control and consistent surface quality across high-volume runs.

Key Features

• CVD diamond coating for extended tool life in abrasive and composite materials
• 4-flute spiral geometry supports both roughing and finishing operations
• 30-degree medium helix angle balances chip evacuation and cutting stability
• 0.25-inch nose radius (ball end) for contour milling and 3D surface work
• Centercutting design allows plunge entry into workpiece material
• Straight-cylindrical shank with tight shank diameter tolerance (-0.0001 / -0.0004 inches) for secure tool holding

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide ball end mill for CNC machining centers and milling machines accepting a 0.5-inch straight-cylindrical shank. Catalog reference: DIALB430-0.500-D3-B.0-Z4.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per OSHA and shop lockout/tagout procedures. Seat the shank fully into the collet or end mill holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout does not exceed the TIR maximum of 0.0005 inches before beginning a cut. CVD diamond-coated tools require dry or minimum-quantity lubrication (MQL) cutting conditions in most composite and graphite applications; consult the tooling engineer before applying flood coolant.
