Accupro 12181361 Square End Mill 9/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181361 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 9/32 inch (0.2813 inch) cutting diameter, a 3/4 inch length of cut, and a 2-1/2 inch overall length. The tool is coated with AlTiN (Aluminum Titanium Nitride) for improved heat resistance and tool life in high-speed cutting applications. With a 40-degree helix angle and spiral flute geometry, it is built for efficient chip evacuation and consistent cutting performance. Solid micrograin carbide construction provides the hardness and rigidity required for demanding ferrous and non-ferrous machining.

This end mill is suited for slot milling, profiling, and contouring operations in CNC machining centers and manual mills. It is configured as a single-end, centercutting tool, making it capable of plunge entry as well as peripheral and face cutting. The 5/16 inch shank diameter accommodates standard collet and end mill holder setups common in both job shop and production machining environments. It is appropriate for use on steels, hardened alloys, stainless steel, and similar materials where AlTiN coating performance is most beneficial.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for elevated heat resistance in high-speed and dry cutting applications
• 40-degree helix angle with spiral flute for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute configuration
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance work

Compatibility

Designed as a standard single-end square end mill suitable for use in CNC machining centers and manual milling machines equipped with 5/16 inch collets or end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a de-energized or locked-out state. Ensure the shank is clean and fully seated in the collet or holder before tightening to the tool holder specification. Inspect the cutting edges for chipping or wear before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
