Accupro 12185265 Square End Mill 7/16 in 5 Flute Carbide

Product Description

The ACCUPRO 12185265 is a double-end, square-profile solid carbide end mill designed for precision milling in ferrous and non-ferrous materials. It measures 0.4375 inches (7/16 inch) in cutting diameter with a 9/16 inch length of cut and a 2-3/4 inch overall length. The tool features five spiral flutes at a 45-degree helix angle and an AlTiN (aluminum titanium nitride) coating that improves heat resistance and tool life in demanding cuts. Micrograin carbide construction provides rigidity and edge retention. Right-hand cut with right-hand flute direction. Centercutting geometry allows plunge entry. Intended for use by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slot milling, peripheral milling, and plunge operations in steel, stainless steel, cast iron, and similar materials. The stub-length profile increases rigidity and reduces deflection in short-reach applications. The double-end configuration extends usable tool life by offering two cutting ends per shank. Typical applications include die and mold work, aerospace component machining, and general precision part production on CNC machining centers and manual mills.

Key Features

• Double-end design provides two usable cutting ends per tool
• 5-flute spiral geometry with 45-degree helix angle for efficient chip evacuation and finish quality
• AlTiN coating enhances heat resistance and extends tool life in ferrous materials
• Micrograin solid carbide construction for rigidity and edge retention
• Centercutting capable — supports plunge and ramp entry
• Stub-length (9/16 inch LOC) reduces deflection in short-reach setups

Compatibility

Designed as a standard-shank solid carbide end mill compatible with 7/16 inch collets, end mill holders, and hydraulic chucks used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Use a properly sized collet or end mill holder matching the 7/16 inch shank diameter and confirm runout with a dial indicator before commencing cuts. Follow machine tool manufacturer guidelines for tool projection and clamping torque ranges appropriate to the holder style in use.
