Accupro 12184003 Ball End Mill 0.3937 in 2 Flute Carbide

Product Description

The ACCUPRO 12184003 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.3937-inch (10 mm) mill diameter and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in a wide range of profiling and contouring tasks. The 2-flute configuration provides a balance of chip clearance and cutting edge strength suitable for both slotting and peripheral milling. Built from micrograin solid carbide, this single-end tool maintains edge integrity at higher feed rates and speeds compared to high-speed steel alternatives.

This ball end mill is well suited for CNC machining centers and manual mills used in job shops, tooling departments, and production environments. The 0.9843-inch (25 mm) length of cut accommodates moderate-depth profiling passes, while the 10 mm shank diameter ensures secure toolholder engagement. The right-hand cutting and right-hand flute direction make it compatible with standard CNC spindle configurations. Machinists working on die and mold work, 3D contouring, and finish profiling will find this geometry appropriate for those tasks.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• 2-flute design balances chip clearance with cutting strength for slotting and profiling
• Uncoated finish suitable for use with cutting fluids on a broad range of workpiece materials
• Single-end configuration with right-hand cut and right-hand spiral flute direction
• 10 mm shank diameter matches 0.3937-inch mill diameter for consistent toolholder fit

Compatibility

Designed as a standard single-end ball nose end mill for use in CNC machining centers and milling machines equipped with toolholders accepting a 10 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tools. Use a clean, undamaged collet or end mill holder to prevent runout and premature tool wear. Verify axial depth of cut and feed rate settings against the workpiece material before initiating a cut.
