Accupro 12184919 Ball End Mill 0.75 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184919 is a solid carbide ball end mill designed for high-performance milling in demanding machining environments. With a 0.75-inch mill diameter, a 3-inch length of cut, and an extra-long 6-inch overall length, this tool reaches deep cavities and complex contours that standard-length end mills cannot access. The 4-flute geometry and 40-degree helix angle promote efficient chip evacuation and smooth cutting action in a wide range of workpiece materials. The micrograin carbide substrate delivers the edge retention and rigidity required for precision profiling, contouring, and finishing passes. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

The 12184919 is suited for 3-axis and multi-axis CNC milling centers where deep-reach ball nose profiling is required. Its single-end configuration and right-hand cutting and flute direction make it compatible with standard CNC toolholders and collet chucks using a 0.75-inch shank diameter. Typical applications include mold and die work, aerospace component profiling, and any contouring operation that requires consistent radial accuracy over a long reach. The uncoated finish makes it a reliable general-purpose option before any application-specific coated variant is considered.

Key Features

• 0.75-inch ball nose diameter with tight mill diameter tolerance of +0.000 to -0.002 inches for consistent radial accuracy
• 3-inch length of cut and 6-inch overall length for deep-cavity and extended-reach applications
• 4-flute spiral geometry with 40-degree helix angle for efficient chip flow and smooth surface finish
• Micrograin solid carbide construction for high rigidity and extended edge life
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Uncoated finish suitable for general-purpose profiling and finishing passes

Compatibility

Designed as an OEM-style replacement and standard tooling selection for CNC milling machines accepting a 0.75-inch round shank in collet chucks, milling chucks, or shrink-fit holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the holder. Verify that the shank is fully seated to the correct gauge length in the toolholder before tightening to prevent runout and premature tool failure. Do not exceed the tool manufacturer's recommended cutting parameters for depth of cut, feed rate, or spindle speed for the workpiece material being machined.
