Accupro 12185184 Square End Mill 9/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12185184 is a solid carbide, double-end square end mill designed for precision milling in metalworking and machining applications. With a 9/64 inch (0.1406 inch) cutting diameter and a 40-degree helix angle, this tool delivers clean, aggressive cuts in hardened and abrasive materials. The AlTiN (aluminum titanium nitride) finish extends tool life in high-temperature cutting environments. Four spiral flutes with a micrograin carbide substrate provide excellent rigidity and edge retention. The stub-length configuration adds stiffness, reducing deflection in tight-tolerance work. This end mill is installed by machinists and CNC operators in job shops, tool rooms, and production machining environments.

This end mill is suited for milling steel, stainless steel, cast iron, and other ferrous materials where heat resistance and edge durability are priorities. The centercutting geometry allows plunge milling as well as peripheral cutting. With a 3/16 inch shank diameter and 2 inch overall length, it fits standard collets and tool holders used in vertical machining centers and CNC mills. The double-end design provides two usable cutting ends, extending the service life per tool.

Key Features

• Double-end design provides two cutting ends per tool
• AlTiN coating for high-temperature and abrasive material performance
• 40-degree helix angle promotes chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry
• Micrograin solid carbide substrate for rigidity and edge retention
• Right-hand cut with right-hand spiral flute, stub length for reduced deflection

Compatibility

Designed for use in standard 3/16 inch collets and compatible tool holders on vertical machining centers and CNC milling machines. No specific model compatibility data was provided by the manufacturer for this part.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention hardware according to the machine manufacturer's specifications. Verify runout with a dial indicator before beginning production cuts.
