Osg 412-1181 Square End Mill 0.1181 in 2 Flute Solid Carbide

Product Description

The OSG 412-1181 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 0.1181 inch cutting diameter, a 0.2362 inch length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. The micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. This is a single-end, right-hand cut tool with a bright, uncoated finish. It belongs to the OSG Series 412 stub-length family and is used by machinists and tool-and-die professionals working on CNC mills and manual knee mills.

This end mill is suited for slotting, profiling, and contouring cuts in applications where a small-diameter, stub-length tool is required for rigidity and reduced deflection. The 0.1181 inch shank diameter matches the cutting diameter, making it compatible with standard collets and tool holders sized for 3 mm or 0.1181 inch shanks. It is a centercutting tool, allowing plunge cutting in addition to peripheral milling. Typical applications include precision machining of small features, mold work, and detailed component machining where tool reach is limited.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows plunge milling operations
• Right-hand cut and right-hand flute direction for standard CNC and manual mill use
• Stub-length body improves rigidity and reduces deflection on small-diameter cuts
• Bright, uncoated finish suitable for general-purpose machining

Compatibility

Designed as an OEM-style solid carbide square end mill for use with standard collets and tool holders accepting a 0.1181 inch or 3 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
