Accupro 12184146 Ball End Mill 0.315 in 2 Flute Carbide

Product Description

The ACCUPRO 12184146 is a single-end ball end mill designed for contour milling, profiling, and 3D surfacing operations in CNC machining centers and manual mills. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for cutting hardened steels, stainless alloys, cast iron, and non-ferrous materials. The 8 mm (0.315 inch) cutting diameter pairs with a 12 mm length of cut, and the tool carries a TiCN coating that reduces friction and extends tool life in demanding cutting environments. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of feed rates.

This end mill is suited for die and mold work, precision part profiling, and finish passes where a ball-nose geometry is required to generate curved surfaces or blend radii. The stub-length configuration keeps the tool stiff and minimizes deflection in short-reach applications. Right-hand cutting and right-hand flute direction make it compatible with conventional CNC setups. Machinists, tool-and-die makers, and precision job-shop operators are the primary users for this style of tooling.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiCN coating reduces friction and increases wear resistance in ferrous and non-ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Stub-length design minimizes tool deflection in short-reach setups
• Single-end ball nose geometry for contour profiling and 3D surfacing
• Right-hand cut and right-hand spiral flutes for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard CNC machining centers and manual mills accepting an 8 mm straight shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the 8 mm shank fully into a collet or end mill holder and torque to the tool holder manufacturer's specification. Verify runout at the cutting edge before beginning a production pass to avoid premature edge wear.
