Accupro 12184247 Ball End Mill 0.25in 2 Flute Carbide

Product Description

The ACCUPRO 12184247 is a single-end ball end mill engineered for precision milling operations in ferrous and non-ferrous materials. Manufactured from micrograin solid carbide, it offers rigidity and wear resistance across a range of machining applications. The tool features a 0.25 inch mill diameter, a 1.5 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for reaching deeper cavities and pockets. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is uncoated and ready for use in applications where coating is not required or where regrinding is anticipated.

This ball end mill is suited for CNC machining centers and manual mills performing contour milling, profiling, slotting, and 3D surface work. The ball nose geometry makes it appropriate for finishing passes on curved surfaces and complex part geometries. The extra-long overall length allows access to deep features that standard-length tools cannot reach. It is installed and operated by machinists, tool-and-die makers, and CNC programmers working in job shop, aerospace, mold-and-die, and general manufacturing environments.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• 0.25 inch mill diameter with mill diameter tolerance of +0.000 to -0.002 inches
• 1.5 inch length of cut and 4 inch overall length for extended reach into deep pockets
• 40-degree right-hand spiral flute for efficient chip evacuation
• Single-end ball nose geometry suited for contouring and 3D surface finishing
• Uncoated finish — compatible with regrinding services

Compatibility

Designed as a direct-fit replacement or new-install tool for standard 0.25 inch collet or end mill holders on CNC machining centers and manual knee mills accepting right-hand cutting tools.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder that matches the 0.25 inch shank diameter; verify shank seating depth per machine tool specifications. Confirm cutting direction is set to right-hand before initiating a cut.
