Accupro 12184164 Ball End Mill 0.3906 in 2 Flute Carbide

Product Description

The ACCUPRO 12184164 is a solid carbide ball end mill designed for precision milling operations in metal and hard-material applications. Built from micrograin solid carbide, this single-end tool features a 0.3906-inch diameter cutting edge and a TiCN (titanium carbonitride) coating that extends tool life by reducing friction and improving wear resistance at elevated temperatures. With a 2-flute configuration and a 40-degree helix angle, it is suited for applications requiring sharp chip evacuation and clean surface finishes in ferrous and non-ferrous materials. Machinists and toolroom operators rely on this geometry for contouring, slotting, and profiling cuts.

This stub-length ball end mill is used in CNC machining centers and manual mills across job shops, tool-and-die operations, and production machining environments. The 0.625-inch length of cut and 7/16-inch shank diameter make it appropriate for shallow-to-medium-depth profiling passes where rigidity is a priority. The right-hand cutting and right-hand spiral flute direction suit standard spindle configurations. Its stub length reduces deflection, which is especially valuable in tight-tolerance finishing work on molds, dies, and contoured part features.

Key Features

• Micrograin solid carbide construction for hardness and thermal stability
• TiCN coating reduces friction and extends tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• 2-flute ball end geometry supports contouring, profiling, and slotting
• Stub-length design minimizes deflection during finish-pass operations
• Single-end configuration with right-hand cut and right-hand flute spiral

Compatibility

Designed for use in CNC machining centers and manual mills with standard 7/16-inch collet or toolholder systems accepting right-hand cutting solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in a clean, properly sized collet or end mill holder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as excessive runout accelerates coating wear and reduces tool life.
