Osg 3131302 Square End Mill 0.0118 in 2 Flute Solid Carbide

Product Description

The OSG 3131302 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. It features a 0.0118-inch cutting diameter and a 0.0177-inch length of cut, making it well suited for micro-milling operations where accuracy is critical. The 0.1575-inch shank diameter provides a stable interface with standard collet systems. Constructed from micrograin solid carbide and finished with OSG WXL coating, this end mill delivers extended tool life in ferrous and non-ferrous materials. With a 30-degree helix angle and right-hand cut geometry, it promotes efficient chip evacuation in fine-detail work.

This end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. Common applications include mold and die work, medical component machining, electronics fabrication, and aerospace part finishing. The centercutting design allows plunge entry, adding versatility in multi-axis setups. Its extended reach configuration provides access in confined pockets or deep-cavity features. Machinists and CNC operators in production and job shop environments are the primary users of this tool.

Key Features

• 0.0118-inch cutting diameter for micro-milling applications
• Micrograin solid carbide construction for rigidity and wear resistance
• WXL coating for extended tool life in a range of workpiece materials
• 30-degree helix angle promotes smooth cutting and chip evacuation
• Centercutting geometry allows direct plunge entry
• Extended reach design for access in deep pockets and confined features

Compatibility

Designed as a direct-fit replacement end mill for CNC machining centers and manual mills accepting a 0.1575-inch round shank in standard ER or precision collet toolholders.

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. Use a calibrated torque wrench and the appropriate collet nut wrench when seating the shank in the collet to avoid runout. At this diameter, even minor runout or improper seating will significantly reduce tool life and surface finish quality.
