Accupro 12184166 Ball End Mill 0.3937 in 2 Flute Carbide

Product Description

The ACCUPRO 12184166 is a single-end ball end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention needed for consistent performance in hardened and abrasive materials. The 0.3937 inch (10 mm) cutting diameter is paired with a 0.5512 inch (14 mm) length of cut and a TiCN coating that reduces friction and extends tool life in ferrous and non-ferrous applications. With a 40-degree helix angle and right-hand cutting direction, it is suited for aggressive material removal with smooth chip evacuation. CNC machinists and tool-and-die professionals are the primary installers.

This end mill is appropriate for profiling, contouring, and slotting operations in a wide range of shop environments, including job shops, production machining, and mold-and-die work. The stub length configuration and 10 mm shank diameter make it a compact, rigid option for applications where tool deflection must be minimized. The 70 mm overall length keeps the tool stiff in close-clearance setups. Right-hand flute direction and spiral flute geometry support consistent cutting performance across a variety of workpiece materials including steel, stainless, aluminum, and cast iron when used with appropriate feeds and speeds.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• TiCN coating reduces friction and extends tool life in ferrous applications
• 40-degree helix angle promotes efficient chip evacuation
• Stub length design minimizes deflection in tight setups
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• Single-end configuration for direct replacement without reconditioning the opposite end

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 10 mm straight shank end mill.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a collet or end mill holder to the manufacturer-specified clamping torque for that holder type. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tooling.
