Accupro 12185091 Square End Mill 7/32 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12185091 is a double-end, square-profile solid carbide end mill designed for precision milling in ferrous and non-ferrous materials. It measures 0.2188 inches (7/32 inch) in cutting diameter with a 7/16 inch length of cut and a 1/4 inch shank diameter, making it well suited for tight-tolerance slotting, profiling, and plunging operations. The 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. An AlTiN coating provides heat resistance and extended tool life in high-temperature cutting environments. Machinists and toolroom operators running CNC machining centers or manual mills will find this a dependable stub-length general-purpose tool.

This end mill is intended for use in machining centers, knee mills, and similar metal-cutting equipment where a stub-length, small-diameter tool is required. The 2-1/2 inch overall length and stub length classification limit deflection, improving accuracy in finish and semi-finish passes. The double-end configuration delivers two usable cutting ends, extending the service interval per tool. It is suitable for slot milling, peripheral milling, and plunge cutting in steel, stainless steel, cast iron, and similar materials where AlTiN coatings perform well.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 40-degree helix angle promotes aggressive chip evacuation
• Double-end design provides two cutting ends per tool
• Centercutting geometry allows direct plunge entry
• Right-hand cut, right-hand flute spiral configuration

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 1/4 inch collets, ER collet chucks, and end mill holders used on CNC machining centers and manual milling machines.

Installation Notes

This tool is installed by qualified machinists familiar with rotating cutting tool setups. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after tightening to minimize premature edge wear. Never exceed the manufacturer-recommended feed and speed parameters for the workpiece material and coating type.
