Accupro 12184007 Ball End Mill 0.4063 in 2 Flute Carbide

Product Description

The ACCUPRO 12184007 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.4063-inch (13/32-inch) cutting diameter and a 1-inch length of cut, this tool delivers accurate contour milling, profiling, and 3D surface work. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for demanding CNC machining environments. This is a single-end, right-hand cutting tool with a right-hand flute direction and an uncoated finish, making it suitable for use with external coolant or cutting fluid as the application requires.

This end mill is suited for use in CNC machining centers, vertical mills, and multi-axis equipment where ball-nose geometry is required for contoured surface finishing, radius milling, and die or mold work. The 7/16-inch shank diameter and 2-3/4-inch overall length fit standard ER and side-lock toolholders common in production and job-shop environments. Typical applications include finishing passes on hardened steel cavities, aluminum contouring, and general-purpose 3D profiling work where a consistent ball radius is critical to part geometry.

Key Features

• Micrograin solid carbide construction for extended tool life in demanding cuts
• 40-degree helix angle promotes efficient chip evacuation and reduces heat buildup
• Ball-nose geometry delivers accurate radii on contoured and 3D surfaces
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility
• Uncoated finish — suitable for use with external coolant on a broad range of materials
• Tight diameter tolerance of +0.000 to -0.002 inches ensures consistent part geometry

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard CNC toolholders accepting a 7/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Seat the shank fully within the toolholder to the recommended grip length and torque the collet or set screw per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use — do not run a damaged carbide tool.
