Osg 3133012 Square End Mill 0.0787 in 2 Flute Solid Carbide

Product Description

The OSG 3133012 is a solid carbide square end mill designed for precision material removal in milling applications. It features a 0.0787-inch cutting diameter, a 0.1181-inch length of cut, and a 0.1575-inch shank diameter. Built from micrograin solid carbide and finished with OSG WXL coating, this end mill delivers consistent edge retention and wear resistance at small diameters. The 30-degree helix angle and right-hand cut geometry support efficient chip evacuation in ferrous and non-ferrous materials. With a center-cutting design and extended reach configuration, it handles both plunge and side-milling operations in tight-tolerance work. Machinists and tool-and-die professionals are the primary users.

This end mill is suited for precision slot milling, contouring, and profiling in CNC machining centers and manual milling machines. The small 0.0787-inch diameter makes it well-suited for fine-detail work, micro-machining, and die-cavity finishing where larger tools cannot reach. The extended reach configuration, with a 0.4724-inch reach length and 1.7717-inch overall length, allows work in deeper pockets without tool-holder interference. It is commonly used in mold-making, aerospace component machining, and precision part fabrication.

Key Features

• 0.0787-inch (2 mm) cutting diameter for fine-detail and micro-machining applications
• Micrograin solid carbide construction for hardness and edge retention
• WXL coating for improved wear resistance and reduced friction
• 30-degree helix angle promotes efficient chip evacuation
• Center-cutting geometry allows direct plunge entry
• Extended reach design with 0.4724-inch reach length for deep-pocket access

Compatibility

Designed as a standard shank square end mill compatible with collet chucks and end mill holders accepting a 0.1575-inch (4 mm) shank diameter on CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the tool holder to minimize runout and prevent pullout under cutting loads. Verify spindle speed and feed rate settings are appropriate for the workpiece material and tool diameter before initiating a cut.
