Osg 414-1181 Square End Mill 0.1181 in 4 Flute Carbide

Product Description

The OSG 414-1181 is a solid carbide square end mill designed for precision milling in metal cutting and machining applications. With a 0.1181 inch (3.00 mm) mill diameter and a 0.2362 inch (6.00 mm) length of cut, this tool is built for tight-tolerance work in small-diameter applications. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and wear resistance suited to demanding materials. This is a centercutting tool, allowing direct plunge entry into the workpiece.

This end mill is well suited for CNC machining centers, vertical mills, and manual milling machines where small-diameter, stub-length tooling is required. The stub length profile provides added rigidity, reducing deflection during cutting passes. Typical applications include slotting, profiling, and side milling in ferrous and non-ferrous materials. It is appropriate for use in tool and die shops, precision machine shops, and aerospace or medical component manufacturing environments where dimensional accuracy is critical.

Key Features

• 0.1181 inch (3.00 mm) mill diameter with matching 3.00 mm shank diameter
• 0.2362 inch (6.00 mm) length of cut — stub length for maximum rigidity
• 4-flute spiral design with 30-degree helix angle for efficient chip flow
• Micrograin solid carbide construction for hardness and edge retention
• Centercutting geometry allows direct plunge milling
• Right-hand cut, right-hand flute — uncoated finish

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and CNC machining centers accepting 3.00 mm shank diameter end mills in the stub length range.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully in a collet or end mill holder rated for the 3.00 mm shank diameter, and verify runout before cutting. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Refer to the machine manufacturer guidelines and applicable shop safety standards for proper tool holding torque and setup procedures.
