Accupro 12181640 Square End Mill 9/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181640 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 9/32 inch (0.2813 inch) mill diameter and a 40-degree helix angle, this tool delivers efficient chip evacuation and clean cutting in ferrous and non-ferrous materials. The AlTiN finish provides thermal resistance and extended tool life under high-speed cutting conditions. Stub length geometry keeps the tool rigid, reducing deflection during demanding cuts. This end mill is installed and operated by machinists and CNC programmers working with vertical machining centers, mills, and related machine tools.

This end mill suits stub-length applications where rigidity is critical and reach requirements are minimal. The 1/2 inch length of cut and 2 inch overall length make it well matched to shallow pocket milling, slotting, and profiling operations. The centercutting design allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups. The micrograin carbide substrate supports higher surface speeds and feeds compared to standard-grade carbide.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature resistance and extended tool life
• 40-degree spiral flute helix for effective chip evacuation
• Centercutting capable — supports direct plunge milling
• Stub length with 1/2 inch LOC reduces deflection in tight setups
• Right-hand cut, right-hand flute — standard CNC orientation

Compatibility

Designed as a stub-length square end mill for use in standard CNC machining centers, knee mills, and manual milling machines accepting a 5/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Use a properly sized collet or end mill holder rated for the 5/16 inch shank diameter and tighten to the holder manufacturer's specification. Inspect the cutting edges and coating for chips or damage before each use.
