Accupro 12185079 Square End Mill 11/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12185079 is a solid carbide, double-end square end mill designed for precision milling in metalworking and machining applications. With an 11/64 inch (0.1719 inch) cutting diameter, a 40-degree helix angle, and an AlTiN (aluminum titanium nitride) coating, this tool delivers high thermal resistance and wear performance in demanding cutting conditions. The spiral flute geometry and micrograin carbide substrate support consistent chip evacuation and edge retention at elevated feeds and speeds. This is a right-hand cut, right-hand flute tool with centercutting capability, making it suitable for plunge entry as well as peripheral and slot milling.

This end mill is suited for use in CNC machining centers and manual mills where small-diameter, tight-tolerance work is required. The stub length configuration provides added rigidity, reducing deflection during cuts on ferrous metals, stainless steel, high-temperature alloys, and similar hard materials. It is a double-end design, offering a second usable cutting end to extend tool life and reduce per-cut tooling cost. Machinists and toolroom operators working in production or job-shop environments are the primary users of this tool.

Key Features

• 11/64 inch (0.1719 inch) cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inch
• AlTiN coating for high heat resistance and extended tool life in hard and abrasive materials
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows plunge milling without a pre-drilled entry hole
• Double-end configuration provides two cutting ends per tool
• Micrograin solid carbide construction for superior hardness and edge retention
• Stub length for increased rigidity and reduced deflection in tight-tolerance applications

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills using 3/16 inch shank collets or compatible tool holders.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for collet torque and runout inspection. Ensure the shank is fully seated in a clean, undamaged collet or tool holder before securing. Power down and lock out the machine spindle before any tool change. Verify spindle RPM and feed rate settings are appropriate for the workpiece material before initiating a cut.
