Accupro 12181822 Square End Mill 1/2 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12181822 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. It features a 1/2-inch cutting diameter, a 1-inch length of cut, and a 40-degree helix angle with a spiral flute geometry. The TiCN (Titanium Carbonitride) coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. Micrograin carbide construction provides the rigidity and edge retention required for long-length cutting scenarios. This tool is installed and used by machinists and CNC operators running milling machines in production and job-shop environments.

This end mill suits long-reach milling operations where a standard-length tool cannot access the full depth of a feature. The 4-inch overall length and 1-inch length of cut make it appropriate for profiling, slotting, and peripheral milling in materials such as steel, cast iron, aluminum, and similar workpiece materials. The centercutting design allows for plunge entry directly into the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance and tool life
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting capable — supports direct plunge milling
• Right-hand cut and right-hand flute for standard spindle compatibility
• Long-length series with 4-inch OAL for extended reach applications

Compatibility

Designed for use in standard 1/2-inch collets, milling chucks, or end mill holders on CNC machining centers and manual knee mills. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Use a properly sized collet or end mill holder rated for 1/2-inch shank tooling and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use. Follow shop-standard speeds and feeds tables for the workpiece material and coating type to avoid premature edge failure.
