Accupro 12182212 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182212 is a solid carbide square end mill designed for precision milling operations in metal cutting, die making, and general machining environments. Built from micrograin carbide with a TiCN (titanium carbonitride) coating, this tool delivers improved wear resistance and surface hardness compared to uncoated carbide. It features three flutes in a spiral configuration with a 40-degree helix angle, producing efficient chip evacuation and smooth cutting action. The centercutting geometry allows for direct plunge entry into the workpiece. This end mill is sold individually and is intended for use by machinists and tooling technicians in CNC and manual milling applications.

This end mill suits ferrous and non-ferrous machining in production and job-shop settings. The long-length body, with a 1.125-inch length of cut and 3-inch overall length, provides extended reach for deeper cavities and pockets while maintaining rigidity. The right-hand cut and right-hand flute orientation are standard for conventional milling setups. Its 0.25-inch shank diameter fits standard collets and end mill holders common to most vertical machining centers and manual knee mills.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiCN coating increases surface wear resistance for extended tool life in hard materials
• 40-degree helix angle promotes smooth cutting and efficient chip removal
• Centercutting design permits direct plunge milling without a pilot hole
• Three-flute spiral geometry balances chip load and cutting speed
• Long-length configuration extends reach for deep pocket and cavity work

Compatibility

Designed for use in standard 1/4 inch collets and end mill holders on CNC machining centers, vertical mills, and manual knee mills. Compatible with right-hand spindle rotation setups standard to most milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before installing or removing the end mill from the holder. Ensure the shank is fully seated and the collet or set-screw holder is torqued to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before each use and replace if wear is visible.
