Accupro 12185109 Square End Mill 7/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12185109 is a double-end square end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide, this tool delivers the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. The AlTiN (aluminum titanium nitride) coating reduces heat buildup and extends tool life during high-speed and dry-cutting applications. With a 2-flute spiral design and a 40-degree helix angle, it promotes efficient chip evacuation and smooth finishes. Centercutting geometry allows the tool to plunge directly into the workpiece. Machinists and tool-and-die professionals typically install this tool in CNC machining centers and manual mills.

This end mill is suited for slotting, profiling, and plunge-milling operations in job shops, production facilities, and tool rooms. The stub-length configuration provides added rigidity, which reduces deflection during aggressive cuts. The double-end design offers two usable cutting ends, extending service life between tool changes. The right-hand cut and right-hand flute orientation is standard for most vertical milling setups. It is appropriate for use in steel, stainless, aluminum, and similar machinable materials where a fine edge and tight tolerances are required.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating extends tool life in high-speed and dry-cutting conditions
• 40-degree helix angle promotes efficient chip evacuation and surface finish quality
• Centercutting geometry enables direct plunge entry without pre-drilling
• Double-end design provides two cutting ends per tool
• Stub-length body reduces deflection for tighter tolerances

Compatibility

Designed as a standard replacement or production end mill for vertical machining centers, CNC mills, and manual milling machines accepting a 7/16 inch straight shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing any end mill. Seat the shank fully in a collet or end mill holder rated for the 7/16 inch diameter and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges and coating before each use; do not run a chipped or damaged tool.
