Osg 3133025 Square End Mill 0.0787in 2 Flute Solid Carbide

Product Description

The OSG 3133025 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.0787-inch cutting diameter and a 0.1181-inch length of cut, this tool is suited for fine detail work and small-profile slots, pockets, and contour passes. The 0.1575-inch shank diameter provides a stable interface with standard collet chucks. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The WXL coating enhances wear resistance and extends tool life in demanding materials. This end mill is installed by machinists and toolroom professionals working on CNC machining centers and manual mills.

This end mill is well-suited for small-bore milling, micro-slotting, and fine profiling applications in both ferrous and non-ferrous materials. The extended reach configuration, with a reach length of approximately 25 mm, allows access to deeper features without sacrificing rigidity. The micrograin carbide substrate supports high-speed feeds and tight tolerances. Typical applications include die and mold work, precision component manufacturing, and prototype machining where small cutter diameters and consistent edge geometry are required.

Key Features

Compatibility

Designed for use with standard collet chucks and tool holders accepting a 0.1575-inch (4 mm) shank diameter on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet and torque the collet nut to the tool holder manufacturer's specification. Verify runout with an indicator before beginning a cut to protect both the tool and the workpiece.
