Accupro 12177179 Ball End Mill 0.5in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177179 is a solid carbide ball end mill designed for precision milling of complex contours, curved surfaces, and 3D profiles in metalworking and machining applications. With a 0.5 inch cutting diameter, 4-flute geometry, and a 40-degree right-hand helix, this tool delivers efficient chip evacuation and smooth surface finishes in ferrous and non-ferrous materials. The micrograin carbide construction provides hardness and wear resistance suited for demanding cutting conditions. At 6 inches overall length with a 4.5 inch extended reach, it is well suited for deep-cavity and hard-to-reach milling operations where standard-length tooling falls short.

This ball end mill fits standard CNC machining centers and manual mills equipped with a 0.5 inch collet or end mill holder. Its long-reach configuration makes it appropriate for die and mold work, contour profiling, and pocket milling where the tool must clear fixtures or workpiece walls without interference. The single-end design and bright uncoated finish make it a practical choice for general-purpose machining before specialized coating is required. Machinists working in job shops, tool rooms, and production environments will find this tool applicable across a range of ferrous and non-ferrous workpiece materials.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 4-flute spiral geometry with 40-degree right-hand helix for efficient chip flow
• Extended reach of 4.5 inches enables deep-cavity and contour milling
• 6 inch overall length with 0.5 inch shank diameter for rigid tool holding
• Bright uncoated finish suitable for general-purpose and pre-coating applications
• Single-end ball nose profile for 3D contouring and curved surface work

Compatibility

Designed as a direct-fit replacement for 0.5 inch shank ball end mills in standard CNC and manual milling setups requiring long-reach tooling with a 4-flute solid carbide configuration.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the spindle is fully powered down and locked before inserting or removing the end mill from the collet or toolholder. Verify tool projection and reach clearance against the workpiece and fixturing before beginning any cutting operation. Extended-reach end mills require reduced feed rates and depth of cut relative to standard-length tools to manage deflection and tool load.
