Osg 402-109411 Square End Mill 7/64 in 2 Flute Carbide Tialn

Product Description

The OSG 402-109411 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide and coated with TiAlN (titanium aluminum nitride), this tool delivers extended tool life and heat resistance at elevated cutting speeds. It features a 2-flute spiral configuration with a 30-degree helix angle and a right-hand cut, right-hand flute geometry. The centercutting design allows both plunge and peripheral milling. The mill measures 0.1094 inches (7/64 inch) in diameter with a 3/8 inch length of cut and a 1/8 inch shank diameter. Machinists, tool and die shops, and CNC operators working in ferrous and non-ferrous materials will find this a reliable, production-capable tool.

The OSG 402-109411 is suited for slot milling, profiling, and contour operations on CNC machining centers and manual mills. Its regular-length geometry and compact 1-1/2 inch overall length make it well-matched for close-tolerance work in dies, molds, and precision components. The 2-flute design promotes chip evacuation in slotting cuts, while the TiAlN coating supports dry or near-dry cutting where thermal load is a concern. This tool is part of OSG Series 402.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiAlN coating provides high-temperature resistance and extended tool life
• 30-degree helix spiral flute for efficient chip evacuation
• Centercutting geometry enables plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute for standard CNC spindle compatibility
• Regular length, compact OAL of 1-1/2 inches for stability in tight setups

Compatibility

Designed as a direct-fit tooling option for standard 1/8 inch collets and tool holders on CNC machining centers and manual milling machines. Part of OSG Series 402.

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 1/8 inch collet or end mill holder, verified for runout before cutting. Follow the machine manufacturer and OSG cutting data recommendations for speed and feed; do not exceed tool rating for depth of cut or chip load.
