Accupro 314079 Square End Mill 3/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 314079 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/4-inch cutting diameter, a 1-inch length of cut, and a 5-inch overall length with a matching 3/4-inch shank. The micrograin carbide substrate provides edge retention under high cutting loads, while the ZrN (zirconium nitride) coating reduces friction and extends tool life compared to uncoated carbide. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is sized and specified for use by machinists and tool-and-die professionals running milling machines or machining centers.

The 314079 suits general-purpose and finishing milling passes in a shop or production environment. With centercutting geometry, it can be plunged directly into a workpiece, making it useful for slotting, profiling, and pocket milling applications. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC and manual milling setups. The 2-flute design provides larger chip gullets, which is advantageous when milling softer materials or when chip clearance is a priority.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating reduces heat buildup and extends cutting life
• 45-degree helix angle for efficient chip evacuation and reduced cutting forces
• Centercutting geometry enables direct plunge entry into the workpiece
• 2-flute configuration provides maximum chip clearance for slotting and pocketing
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/4-inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation of end mills should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the milling machine spindle is fully stopped and power is locked out before changing tooling. Use a properly sized collet or end mill holder that matches the 3/4-inch shank diameter and torque the retention mechanism according to the holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
