Accupro 12179633 Roughing End Mill 5/16 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 12179633 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from micrograin solid carbide, it delivers hardness and wear resistance suited for demanding cutting environments. The tool measures 5/16 inch in diameter with a 1/2-inch length of cut and a 2-inch overall length. An AlTiN coating provides thermal protection and reduces friction at elevated cutting speeds. The integrated chipbreaker geometry breaks chips into smaller segments to prevent packing, improve evacuation, and reduce cutting forces. Right-hand cutting and right-hand flute direction are standard. This tool is installed by machinists and toolroom technicians in CNC machining centers and manual mills.

The 12179633 is suited for roughing passes in ferrous and non-ferrous materials where rapid stock removal is the priority. Its stub length profile provides increased rigidity, making it appropriate for applications requiring reduced deflection and vibration. The coarse pitch and chipbreaker geometry together support high feed rates in slotting and profiling operations. Centercutting capability allows plunge entry directly into the workpiece. This tool is used in job shops, production machining, and maintenance environments handling general-purpose milling work on steel, stainless, cast iron, and similar materials.

Key Features

• Micrograin solid carbide construction for hardness and extended tool life
• AlTiN coating for thermal resistance and reduced friction at high cutting speeds
• Chipbreaker geometry for efficient chip breaking and improved evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Stub length profile increases rigidity and reduces deflection
• Right-hand cutting and right-hand flute direction for standard milling applications

Compatibility

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

Installation Notes

Installation is performed by machinists or toolroom personnel. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the collet bore and shank for runout before use. Always ensure the machine spindle is fully stopped and the machine is in a safe state before changing tooling.
