Accupro 12184827 Ball End Mill 0.4375 in 4 Flute Carbide

Product Description

The ACCUPRO 12184827 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous metals, hardened steels, and similar materials. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention needed for high-speed finishing and profiling passes. The TiCN coating reduces friction and improves wear resistance for extended tool life. At 0.4375 inches in diameter with a 0.625-inch length of cut and a 40-degree helix angle, the 12184827 is suited for contouring, slotting, and 3D surface work on CNC machining centers. Machinists and toolroom operators working in production or job-shop environments are the primary users.

This ball end mill is used in CNC milling applications where a full-radius cutting profile is required for 3D contouring, cavity milling, and die and mold work. The stub-length configuration provides added rigidity, making it appropriate for setups where minimizing deflection is a priority. The right-hand cutting and right-hand spiral flute geometry suit standard spindle rotation on vertical and horizontal machining centers. The 0.4375-inch shank diameter matches the mill diameter, allowing direct chuck or collet holding in common toolholding systems.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• TiCN coating reduces friction and extends tool life in ferrous materials
• 40-degree helix angle promotes smooth chip evacuation and surface finish
• 4-flute spiral design balances chip load and material removal rate
• Stub-length configuration increases rigidity and reduces deflection
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

Designed as a standard shank ball end mill compatible with CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 0.4375-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut.
