Accupro 12184576 Ball End Mill 0.125 in 4 Flute Carbide

Product Description

The ACCUPRO 12184576 is a solid carbide ball end mill designed for precision milling operations in metal and alloy workpieces. The 0.125 inch cutting diameter and 4-flute spiral geometry deliver smooth chip evacuation and fine surface finishes in both roughing and finishing passes. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in dry or high-speed cutting environments. The 40-degree helix angle reduces cutting forces and improves chip flow. This tool is intended for use by machinists and tooling professionals operating CNC mills and manual milling machines.

This end mill suits applications in ferrous metals, hardened steels, stainless steel, and similar difficult-to-machine materials where heat buildup is a concern. The 0.5 inch length of cut accommodates moderate-depth profiling, slotting, and contouring. The single-end design provides a fixed reference geometry for tool-length offset setup. The 0.125 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in CNC machining centers and manual mills used in job shops, aerospace component manufacturing, and die-and-mold work.

Key Features

• 0.125 inch ball-nose cutting diameter for fine detail and contour work
• 4-flute spiral geometry supports higher feed rates and improved finish quality
• AlTiN coating provides elevated heat resistance for dry and high-speed machining
• 40-degree right-hand helix reduces radial cutting forces
• Micrograin solid carbide substrate for rigidity and wear resistance
• Single-end design with 1.5 inch overall length for consistent tool-length offset setup

Compatibility

Designed for use in standard ER collet chucks and end mill holders accepting a 0.125 inch shank diameter, as used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully in the collet or holder and torque the retention hardware per the toolholder manufacturer specification. Verify tool runout with a dial indicator before beginning production cuts, as excessive runout accelerates wear on small-diameter end mills.
