Accupro 12185224 Square End Mill 9/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12185224 is a solid carbide, double-end square end mill designed for precision milling operations in metalworking and machining environments. With a 9/32-inch (0.2813-inch) cutting diameter and a 40-degree helix angle, it is built for efficient chip evacuation and smooth cutting performance. The four-flute, spiral-flute geometry supports both slotting and peripheral milling. The uncoated micrograin carbide construction is suited for applications where tight tolerances and sharp cutting edges are priorities. This tool is installed and used by machinists and CNC operators working in job shops, tool rooms, and production machining environments.

This end mill is suited for use on CNC machining centers and manual knee mills where a stub-length tool is preferred for rigidity. The 1/2-inch length of cut and 2-1/2-inch overall length make it appropriate for shallow-to-moderate depth milling passes. The 5/16-inch shank diameter fits standard ER and end mill holders commonly found in production and toolroom setups. Right-hand cut and right-hand flute orientation are standard for conventional spindle rotation. The double-end design provides two usable cutting ends, extending tool life between replacements.

Key Features

• Solid micrograin carbide construction for wear resistance and edge retention
• Double-end design offers two cutting ends per tool
• 40-degree helix angle promotes efficient chip evacuation
• Four spiral flutes support slotting and peripheral milling
• Centercutting capability allows plunge entry into workpiece
• Stub length (2-1/2-inch OAL) maximizes rigidity in the cut

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 5/16-inch end mill holders and ER collet chucks used in CNC machining centers and manual milling machines.

Installation Notes

Installation of end mills should be performed by qualified machinists following safe tool-change procedures. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and properly torqued in the holder per the holder manufacturer specification. Inspect the cutting edges for chips or damage before each use.
