Accupro 12179012 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179012 is a solid carbide square end mill designed for precision milling in metal cutting and machining operations. Built from micrograin solid carbide with a nACRo finish, it delivers consistent cutting performance in hardened and abrasive materials. The 4-flute, spiral design operates at a 40-degree helix angle for efficient chip evacuation and smooth surface finishes. At 0.375 inches in diameter with a 0.625-inch length of cut and a 2-inch overall length, this is a stub-length tool suited for rigid, high-tolerance work. Centercutting geometry allows plunge entry, adding to its versatility on CNC machining centers and manual mills.

This end mill is intended for professional machinists and tool-and-die tradespeople working in job shops, production environments, or maintenance machining. The stub length and 0.375-inch shank diameter make it well suited for applications where rigidity and minimal deflection are priorities, such as shoulder milling, slotting, and pocketing in ferrous and non-ferrous materials. The right-hand cut and right-hand flute configuration match standard CNC spindle rotation. The nACRo coating helps extend tool life in demanding cutting conditions.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance
• nACRo finish for extended tool life in abrasive and hard materials
• 40-degree helix angle promotes efficient chip evacuation
• 4-flute spiral design supports higher feed rates and improved surface finish
• Centercutting capability allows direct plunge entry
• Stub length provides enhanced rigidity and reduced deflection

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/8-inch collets and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 0.375-inch shank fully and evenly in a compatible collet or end mill holder and torque the collet nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
