Accupro 12184640 Ball End Mill 11/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12184640 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With an 11/32 inch (0.3438 inch) mill diameter and a 4-flute spiral configuration, it delivers smooth chip evacuation and consistent surface finishes on ferrous and non-ferrous materials. The micrograin carbide substrate provides wear resistance and edge retention at higher feed rates. The bright/uncoated finish makes it well suited for applications where coating buildup or heat sensitivity is a concern. This tool is installed and operated by machinists and CNC tool setters in production shop environments.

This end mill fits standard milling operations requiring a 3/8 inch shank in a collet or end mill holder. The 7/8 inch length of cut and 2-1/2 inch overall length make it appropriate for shallow-to-medium depth profiling, slotting, and contouring passes in both manual and CNC milling machines. The single-end configuration is typical for production tooling where the cutting end is replaced rather than reversed. Right-hand cutting and right-hand flute direction are standard for conventional CNC mill spindle rotation.

Key Features

• Solid micrograin carbide construction for extended tool life and edge stability
• 4-flute spiral design promotes efficient chip removal and improved surface finish
• 40-degree helix angle supports aggressive feed rates in harder materials
• Bright/uncoated finish suitable for aluminum, brass, and other non-ferrous applications
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Single-end tool with consistent mill diameter tolerance of +0.000/-0.002 inch

Compatibility

Designed for use in CNC and manual milling machines with a 3/8 inch collet or end mill holder. Suitable for profiling, contouring, and slotting operations in a range of materials.

Installation Notes

This tool is installed by machinists or CNC setup technicians using a compatible 3/8 inch collet or shrink-fit holder. Ensure the spindle is fully stopped and locked before inserting or removing the tool. Verify runout and tool projection before beginning a cut. Follow machine manufacturer guidelines and shop safety standards for tooling changes and speeds and feeds selection.
