Accupro 12179049 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179049 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 0.5 inch cutting diameter with a 3 inch length of cut and a 6 inch overall length, making it well suited for deep slotting and profiling work. The nACRo coating provides enhanced lubricity and wear resistance at elevated cutting temperatures, extending tool life in demanding machining environments. This end mill is installed and operated by machinists and toolroom professionals in production and job shop settings.

This end mill is intended for use on vertical and horizontal milling machines, machining centers, and CNC mills performing side milling, slotting, and contouring operations. The 4-flute, right-hand cut, right-hand spiral configuration with a 40-degree helix angle delivers efficient chip evacuation and a smooth surface finish. The centercutting design allows direct plunge entry into the workpiece. Micrograin carbide construction supports higher surface footage and improved edge retention across a wide range of materials.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• nACRo coating for improved wear resistance and reduced heat buildup at the cutting edge
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill compatibility
• 4-flute design balances material removal rate with surface finish quality

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for standard 0.5 inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 0.5 inch shank fully in the holder and torque set screws or collet nuts to the toolholder manufacturer specifications. Verify runout at the cutting edge before engaging a cut, as excessive runout will accelerate edge wear and reduce tool life.
