Accupro 12179746 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12179746 is a solid carbide square end mill designed for precision milling in metal cutting and machining applications. It features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length with a 0.5 inch shank. Constructed from micrograin solid carbide and coated with a ZrN (zirconium nitride) finish, this end mill offers improved wear resistance and extended tool life in demanding cuts. The 40-degree helix angle and 3-flute spiral geometry promote efficient chip evacuation and smooth cutting action. It is centercutting, allowing direct plunge entry into workpieces without a pre-drilled hole.

This end mill is suited for milling ferrous and non-ferrous materials in production and job shop environments. The long-length configuration with a 2 inch length of cut makes it appropriate for deep pocket milling, slotting, and profiling operations where standard-reach tooling falls short. It is installed and operated by machinists and CNC programmers working on vertical machining centers, manual knee mills, and similar machine tools. Right-hand cut and right-hand flute orientation is standard for conventional spindle-up milling setups.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating provides a hard, low-friction surface for extended tool life
• 40-degree helix angle promotes aggressive chip evacuation and reduced cutting force
• 3-flute design balances chip load capacity with core strength
• Centercutting geometry enables direct plunge milling without pilot drilling
• Long-length classification with 2 inch LOC for deep pocket and slot applications

Compatibility

Designed as a direct-fit replacement for standard 1/2 inch shank square end mills in CNC and manual milling machine tool holders with a 1/2 inch collet or end mill holder.

Installation Notes

This tool is installed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder, torquing to the tool holder specification per the manufacturer. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear and reduces part accuracy.
