Kennametal 4173915 Ball End Mill 0.5 in 2 Flute Solid Carbide

Product Description

The KENNAMETAL 4173915 is a ball end mill from the GOmill UEBD series, designed for high-performance milling in demanding metalworking applications. Built from fine-grain solid carbide and coated with AlTiN via PVD process, this tool delivers reliable cutting performance on steel, stainless steel, cast iron, high-temp alloys, and hardened materials. The 0.5-inch diameter with a 2-flute, right-hand spiral configuration and 30-degree medium helix produces stable chip evacuation and consistent surface finishes. Center-cutting geometry enables direct plunging and ramping operations without a pre-drilled entry point. Licensed machinists and CNC operators in job shops and production environments rely on this stub-length design for rigidity in tight-tolerance applications.

The 4173915 is suited for both roughing and finishing operations across a broad range of ferrous workpiece materials. Its short stub-length design minimizes deflection, making it appropriate for applications where tool overhang must be kept to a minimum. The straight-cylindrical shank seats directly into standard ER collets or end mill holders with a 0.5-inch bore. The single-end configuration and fine-grain carbide substrate are optimized for production milling where dimensional consistency is critical. This tool is not recommended for reconditioning after wear.

Key Features

• AlTiN coating applied by PVD process for heat resistance and extended tool life in ferrous materials
• Fine-grain solid carbide substrate provides edge stability and wear resistance
• Center-cutting design supports plunging and ramping operations
• 30-degree medium helix with right-hand flute direction for efficient chip removal
• Stub-length construction reduces deflection and improves cutting stability
• Compatible with workpiece material codes P, M, K, S, and H covering steel through hardened alloys

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 0.5-inch end mill holders, ER collet chucks, and hydraulic or shrink-fit toolholders accepting a straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, high-temp alloys, and hardened materials per the GOmill UEBD series specification. Manufacturers catalog number UEBD0500J2A.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician familiar with end mill toolholding practices. Verify the holder bore tolerance matches the shank diameter tolerance of +0.0000/-0.0043 inches before seating. Ensure the machine spindle is fully stopped and de-energized before changing tooling. This tool is not recommended for reconditioning; replace at end of service life.
