Accupro 12179287 Ball End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12179287 is a solid carbide ball end mill designed for precision milling in demanding machining environments. Built with four flutes and a 40-degree helix angle, it promotes efficient chip evacuation and smooth cutting action. The mill diameter is 0.1875 inches (3/16 inches) with a matching 3/16-inch shank diameter. Overall length is 3 inches, and the length of cut is 1-1/8 inches. An nACRo coating provides thermal and wear resistance, extending tool life in high-speed and high-temperature cutting applications. This tool is suited for machinists and tooling professionals working in production or job-shop settings.

This ball end mill is intended for right-hand cutting with right-hand spiral flutes on a single-end configuration. The micrograin carbide substrate supports tight tolerance work, with a mill diameter tolerance of plus 0.000 and minus 0.002 inches and a shank diameter tolerance of minus 0.0001 to minus 0.0004 inches. It is well-suited for profiling, contouring, slotting, and finishing passes in ferrous and non-ferrous materials where the nACRo coating provides an advantage in hardened or abrasive stock.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• nACRo coating for extended tool life in high-heat and abrasive cutting conditions
• 40-degree helix angle promotes smooth chip flow and reduced cutting forces
• Four-flute design balances material removal rate with surface finish quality
• Tight diameter tolerances support close-tolerance profiling and finishing work
• Single-end, right-hand cut configuration standard for CNC and manual mill setups

Compatibility

Designed as a standard 3/16-inch shank ball end mill compatible with collet chucks, end mill holders, and tool holders accepting a 3/16-inch round shank on vertical machining centers, CNC mills, and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the holder manufacturer specification. Inspect the cutting edges and coating for damage before use.
