Sgs 31237 Ball End Mill 0.5in 4 Flute Solid Carbide Altin

Product Description

The SGS 31237 is a double-end ball end mill designed for precision milling in demanding machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited for high-speed cutting operations. The tool features a 0.5-inch mill diameter, a 0.625-inch length of cut, and a 3.0-inch overall length. With 4 flutes in a right-hand spiral configuration and a 30-degree helix angle, it produces efficient chip evacuation and smooth surface finishes. Machinists and tool-and-die professionals working with challenging workpiece materials rely on this geometry for consistent performance at depth.

The SGS 31237 is suited for milling operations across a broad range of workpiece material categories including hardened steels, cast irons, stainless steels, non-ferrous metals, structural steels, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. Its stub-length classification makes it appropriate for applications where rigidity is prioritized over reach, such as contour milling, pocket milling, and profiling in CNC machining centers. The double-end configuration extends usable tool life before replacement is required.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• AlTiN coating provides oxidation resistance and extended tool life at elevated cutting temperatures
• Double-end design doubles usable cutting ends per tool
• 4-flute, 30-degree right-hand spiral geometry for efficient chip flow and surface finish
• 0.5-inch shank diameter with tight tolerance (+0.00000 to -0.00043 inches) for secure holder fit
• Mill diameter tolerance held to +0.000 to -0.002 inches for dimensional accuracy

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 0.5-inch shank; belongs to SGS Series 14B stub ball end mills.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet or end mill holder rated for the 0.5-inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Follow your machine tool manufacturer guidelines for runout tolerances and tool projection length. Extended reach and coolant-through features are not available on this tool, so confirm application requirements before setup.
