Accupro 12184877 Ball End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12184877 is a solid carbide ball end mill designed for precision milling of contoured surfaces, pockets, and three-dimensional profiles. With a 7/16 inch (0.4375 inch) mill diameter and a 2 inch length of cut, this tool delivers consistent material removal in demanding machining environments. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for high-feed operations in ferrous and non-ferrous materials. This is a single-end, uncoated tool in a long-length configuration.

This ball end mill is suited for CNC machining centers and manual mills where contour milling, die work, and profiling operations require a reliable long-reach tool. The 7/16 inch shank diameter matches the mill diameter for straightforward collet or end mill holder setup. It is appropriate for job shops, tool-and-die operations, mold making, and production environments where tight tolerances and surface finish quality are priorities. Licensed machinists and CNC operators in both prototype and production settings are the primary users.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 4-flute, right-hand spiral design with 40-degree helix for efficient chip evacuation
• Ball end geometry for contour milling, 3D profiling, and radius floor finishing
• Long-length configuration with 2 inch LOC for deeper reach into pockets and cavities
• Uncoated finish suitable for a broad range of workpiece materials
• Mill diameter tolerance of +0.000 to -0.002 inches for consistent fit and repeatability

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 7/16 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer torque and runout specifications for end mill holders or collets. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut. Always confirm workpiece fixturing is secure before engaging the tool.
