Accupro 12180923 Ball End Mill 0.125 in 2 Flute Carbide

Product Description

The ACCUPRO 12180923 is a solid carbide ball end mill designed for precision milling operations in metal cutting and finishing applications. With a 0.125 inch cutting diameter and a 0.125 inch length of cut, this tool is built for tight-tolerance profiling, slotting, and contour work. The two-flute geometry paired with a 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An AlTiN coating provides thermal resistance and surface hardness, extending tool life in ferrous and hardened materials. Micrograin carbide construction delivers rigidity and edge retention at elevated cutting speeds. Licensed machinists and toolroom operators install this type of end mill in CNC machining centers and manual mills.

This end mill is suited for precision work in ferrous metals, hardened steels, stainless alloys, and similar materials where a ball-nose profile is required for 3D contouring, radius floors, or blended surfaces. The single-end configuration and 0.125 inch shank diameter make it compatible with standard collet systems used in CNC vertical machining centers and high-speed spindle setups. The 3 inch overall length provides adequate reach for most shallow-cavity and surface-finish operations without sacrificing rigidity at this diameter.

Key Features

• 0.125 inch cutting diameter with matching 0.125 inch length of cut for precision profiling
• AlTiN coating for thermal resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate for edge retention and rigidity
• 30-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Two-flute spiral geometry supports chip clearance in slotting and contouring passes
• Right-hand cut and right-hand flute direction — standard CNC spindle rotation compatible

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills using standard 1/8 inch collet or end mill holders with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the collet or tool holder to the minimum insertion depth required by the holder manufacturer before tightening. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after installation to protect edge integrity at this diameter.
