Accupro 12183114 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183114 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 5/8 inch cutting diameter, a 2-1/8 inch length of cut, and a 4-flute spiral geometry with a 40-degree helix angle. The TiCN (Titanium Carbonitride) coating improves surface hardness and reduces friction at the cutting edge, extending tool life in production environments. Micrograin carbide construction provides rigidity and resistance to chipping. This tool is centercutting, allowing direct plunge entry, and is offered in a long-series configuration with a 4-5/8 inch overall length.

This end mill is suited for milling slots, pockets, profiles, and contour passes on CNC machining centers and manual knee mills. The long-series length makes it appropriate for applications requiring extended reach into deep pockets or fixtures where a standard-length tool cannot clear. Right-hand cut and right-hand spiral flutes are standard for conventional and climb milling with a right-hand spindle. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance environments will find this geometry well-matched to general-purpose and finish milling tasks.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating increases surface hardness and reduces built-up edge
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• Long-series overall length of 4-5/8 inches for extended reach applications
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 5/8 inch collets, end mill holders, and shrink-fit tooling systems used on CNC machining centers and manual mills with right-hand spindles.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked before mounting or removing the tool. Seat the shank fully and evenly in the holder to the minimum recommended engagement depth for the holder type in use. Verify runout with a dial indicator before production cuts; excessive runout accelerates edge wear and reduces surface finish quality.
