Accupro 12184264 Ball End Mill 0.5625 in 2 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12184264 is a solid carbide ball end mill designed for high-performance milling in hardened and abrasive materials. With a 0.5625 inch (9/16 inch) mill diameter and a 3 inch length of cut, this single-end tool delivers reach and rigidity for profiling, contouring, and finishing passes in ferrous and non-ferrous metals. The AlTiN coating increases surface hardness and heat resistance, extending tool life in dry and semi-dry cutting conditions. Micrograin carbide construction provides the edge retention and toughness required for demanding production environments. Machinists and CNC programmers use this style of end mill for 3D contour work, cavity milling, and die and mold applications.

This end mill suits vertical and horizontal CNC machining centers running tool steel, stainless steel, cast iron, and high-temperature alloys. The extra-long 6 inch overall length allows access to deeper pockets and tall workpiece features without requiring extended-reach adapters. The 9/16 inch shank diameter matches standard ER and side-lock toolholders common in production shops. Right-hand cutting and right-hand spiral flutes make this a direct fit for conventional CNC spindle rotation. It is sold as a single-end tool, so once the cutting end is worn, the full tool is replaced.

Key Features

• 0.5625 inch (9/16 inch) ball nose diameter for radius profiling and 3D contouring
• 3 inch length of cut for deep-reach pocket and cavity work
• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide construction for edge retention and rigidity
• 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• Extra-long 6 inch overall length for tall workpiece and deep-cavity access
• 2 flute, right-hand spiral design optimized for finishing passes

Compatibility

Designed as an OEM-style replacement and direct-fit solid carbide ball end mill for CNC machining centers accepting a 9/16 inch shank diameter in standard ER collet chucks, milling chucks, and side-lock toolholders.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the tool. Clean the toolholder bore and shank with a lint-free cloth before assembly to prevent runout from contamination. Confirm proper torque on the collet nut or set screw per the toolholder manufacturer specification before initiating a cutting program.
