Osg 3131810 Square End Mill 0.0315 in 2 Flute Solid Carbide

Product Description

The OSG 3131810 is a solid carbide square end mill engineered for precision milling in demanding metalworking and machining applications. With a 0.0315-inch (0.8 mm) mill diameter, a 0.0472-inch length of cut, and a 0.1575-inch shank diameter, this is a micro end mill built for tight-tolerance work. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces in difficult materials. The WXL coating improves wear resistance and extends tool life in hardened steels and other abrasive workpiece materials. This tool is installed and run by machinists and CNC tooling professionals on vertical machining centers and precision milling machines.

The OSG 3131810 is suited for micro-milling operations requiring fine detail, tight dimensional tolerances, and consistent surface finish. The extended reach design and 10 mm reach length allow access to deeper features without sacrificing rigidity for the cutting diameter. The 45 mm overall length and 4.00 mm shank diameter make it compatible with standard collet systems used in CNC machining centers. This end mill is appropriate for production and prototype work where micro-geometry accuracy is critical.

Key Features

• 0.0315-inch (0.8 mm) mill diameter for micro-scale precision milling

• 30-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Center-cutting capable, allowing plunge entry into workpiece
• Extended reach design with 10 mm reach length for access to deeper features
• Right-hand cut, right-hand flute, 2-flute configuration

Compatibility

Designed for use with standard collet toolholding systems accepting a 4.00 mm (0.1575-inch) shank diameter, as found on CNC vertical machining centers and precision milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully and evenly in the collet to the recommended grip depth to prevent pullout under cutting loads. Verify runout with a dial indicator before beginning production cuts, as excessive runout will accelerate wear on a micro-diameter tool.
