Accupro 12179760 3/4 in Square End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12179760 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/4-inch cutting diameter, a 1-inch length of cut, and a 3/4-inch shank diameter with a 3-inch overall length. The three-flute spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) finish improves surface hardness and heat resistance, extending tool life in moderate to high-speed applications. Centercutting capability allows plunge milling in addition to standard peripheral cuts. This tool is intended for use by machinists and CNC operators working in production or job-shop settings.

The 12179760 is suited for slotting, profiling, and plunge operations on ferrous and non-ferrous materials. Its stub-length profile increases rigidity, making it a practical choice for applications where deflection and chatter need to be minimized. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual mills. Micrograin carbide construction supports tight tolerances and consistent performance across repeat production runs.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating increases surface hardness and thermal resistance
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design enables plunge milling capability
• Three-flute spiral geometry balances chip load and finish quality
• Stub-length profile reduces deflection in tight setups

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder and verify runout with a dial indicator before cutting. Follow machine tool manufacturer guidelines for tool overhang and clamping torque.
